Quads & Doubles Volleyball - Competitive BB+/A
Let's get together to play some competitive quads and doubles volleyball.
**COST**: FREE
**Court Type**: Outdoor grass
**Minimum Skill Requirements**: BB+ (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details)
Attention:
1. This event is **NOT on a first come-first serve** basis and players with higher skill level and players who can bring a net/ball will get priority over others on the wait list.
2. Since skill levels are **self-reported**, some new attendees may not meet the expected level. For doubles, we encourage you to choose a partner you can enjoy the game with, and since this a competitive event, it is okay if you make a strong team and win all the games.
3. Each person must help set up and take down one net, leaving some nets unset for latecomers.
4. Please answer all questions, so it's helpful for us to organize the event.

Sunday Worship Service
## **Sunday Worship: Encountering God’s Word**
Join us every **Sunday at 10:45 AM** for a powerful time of worship, prayer, and deep biblical engagement. Our Sunday service is the heart of our community, where we gather to honor God and equip ourselves for the week ahead through the transformative power of the Gospel.
***
### **What to Expect**
* **Christ-Centered Worship:** We begin our time together by lifting our voices and hearts, creating a space to experience the presence of the Holy Spirit through song and prayer.
* **Exegetical Preaching:** We value the depth of Scripture. Our sermons focus on unfolding the Bible verse-by-verse, providing clear theological insights and practical applications that speak to the challenges of modern life.
* **A Welcoming Community:** At Bethel, you aren't just a face in the crowd. You’ll find a diverse family of believers dedicated to walking together in love, grace, and mutual support.
* **A Call to Action:** We believe faith should move us. Every service concludes with an encouragement to take the hope of Christ out into our neighborhoods, workplaces, and families.
### **Plan Your Visit**
Whether you are wearing your "Sunday best" or coming in casual attire, you are welcome here. We believe that no matter where you are in your spiritual journey, God has a message of grace waiting for you.

ASL Brunch on Sundays in Greenbelt
Join our ASL Brunch on Sundays in Greenbelt! All ASL users and learners are welcome.
Brunches are alternately held at two restaurants in Greenbelt, both in the same town plaza.
ODD WEEKS: 1st, 3rd, and 5th Sundays, we meet at Cedars of Lebanon, 103 Centerway.
EVEN WEEKS: 2nd and 4th Sundays, we meet at New Deal Café,113 Centerway.
We are the Greenbelt ASL Community, a group of both Deaf and hearing people who hang out, chat about everyday goings on, trade stories, get to know each other better, and of course, enjoy food together. Many members use ASL as their primary language, several are interpreters or other fluent ASL users, while others are ASL learners who wish to improve their skills while making new friends.
Before or after brunch, you can visit the farmer's market and small coop grocery store in the plaza.
Please RSVP so we can contact you via email if needed.
Our group is on Facebook as Greenbelt ASL Community. Some longtime Brunch attendees don't mark their attendance here, so feel free to stop by even if you don't see others who have RSVP'd on Meet-up.
Introductory Clinic
As a reminder, since Freedom Plaza is under construction, we will meet at the plaza in front of The International Trade Center near the National Children's Museum (on Pennsylvania Ave).
We'll begin with going over a few drills (varies week to week). The skills we drill will be for the first 30 minutes.
For the second half, we will casually skate down the bike lanes on Pennsylvania Avenue from the plaza to the U.S.Capitol and stop at 3rd St. and then skate back the same route.
This route is about 2 miles in total and is perfect for those who are new to skating in the city but feel comfortable on skates in a parking lot or roller rink. This is also great if you wish to start with shorter routes to increase your physical fitness or stamina for some of the other routes. This is an excellent opportunity to prepare to skate with others on the road. You will also get to meet skaters who will arrive for the Intermediate and Advanced skate routes following the introductory skate.
This is great training to feel prepared for the Tuesday Night and Friday Night Skate!
Route:
http://www.gmap-pedometer.com/?r=7653831
Inline skates (rollerblades), roller skates (quads), bicycles, unicycles, skateboards, longboards and other similar modes of transportation are welcome to join.
Helmet, wrist guards, elbow pads, and knee pads are required. Skate at your own risk.
Children under 18 must be accompanied by an adult for the duration of the session.
Volleyball - B/BB - Quincy Park
If you’ve already learned the basics of volleyball and want to keep improving your skills while having fun, this event is for you!
**Skill Level:** Advanced Beginner (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details).
**Reminders**
1. Attendance: We’ve noticed that the waitlist is growing, so please make sure your name is on the Going list if you plan to play. Our number of nets is limited so this helps avoid too many rotations. If your name is on the list but you don’t show up, it will count as an absence according to Smiley Social rules. Please update your RSVP at least 12 hours in advance if your plans change.
2. Waitlist: The waitlist is not first come first serve. We prioritize regular attendees, and will fill empty spots with new faces closer to the event date.
3. Injuries: Play safely and be mindful of others on the court. Respect positions and avoid risky moves that could lead to injury. If you’re not sure the ball is yours, call it before going for it to avoid collisions.
4. Game Rules: Let’s follow the basic volleyball rules, especially the three-touch rule so we can play properly and improve as a team!

Share a book, meet a friend
We are going to talk about the books we read—any books, from any genre. Whether it’s fiction or nonfiction, classic literature or something modern, everyone is welcome to share their thoughts, impressions, and favorite passages. It’s a relaxed and friendly conversation where we can discover new ideas and enjoy each other’s perspectives.

Read & Reflect: A Social Reading Circle.
Shared Pages, Shared Insights.
📚 Do you love reading, but wish you had a structure and a community to share your insights with?
Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café.
Here’s how it works:
First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you.
Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections.
Why join?
Add structure to your reading habit.
Discover new books, authors, and ideas through others’ choices.
Build real connections by sharing and listening deeply.
Socialize around something meaningful instead of small talk.
Dim Sum Brunch in Rockville
Corner Bites
I’m excited to announce our next culinary outing! We will be heading to Corner Bites in Rockville, MD, to enjoy some authentic Cantonese cuisine.
Corner Bites is a popular dim sum restaurant in Rockville, Maryland, known for its authentic Cantonese cuisine, including classic items like har gow, siu mai, and roast duck, served in a modern setting with order-by-the-menu service rather than carts.
Monthly Culinary Meetup Note:
If you were a previous no show or canceled on the day of when there's a waitlist, you're not guaranteed a seat. - Mellisa
BB and above players only up to 12 players
# Today's meetup is limited to 12 BB and above only players and 2x2, 3x3 or 4x4 play only. Please help us keep this day limited and enjoy the open play on the other days if you or your friend are not BB or above. People make plans and travel to show up on limited days for limited play because it is limited to experienced players. Please do not show up if you are on the waitlist without checking first, or try to play 5's or 6's, with your friend that is learning how to play, or because it is not full with 12 players if you or your friend are not BB or above. We’d rather play with 9 experienced players on these limited days than open it up to beginners, friends that are learning, etc. There are other open days for that, and they are fun too.
Sundays In The Park series
We meet on Sundays at 8 a.m. for training runs on some of DC's best trails, including Rock Creek Park and the surrounding area. We typically meet at either Peirce Mill in Rock Creek Park, or Roosevelt Island, depending on the route.
Details of the weekly schedule can be found here: https://new.vhtrc.org/runs/sip
We hope you can join us for a run! All paces and levels of trail experience are welcome for these runs, which range in distance from 6 to 9 miles.
Meaningful Conversation and Coffee - Northside Social Falls Church
**Join us in Falls Church for conversations that go beyond small talk.**
Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room.
There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique.
MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech.
Come ready to share, reflect, and connect with others in Falls Church who are also seeking deeper conversations.

Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information
A co-hosted event by ProductTank Columbus & Women in Product Columbus
💡 About the Workshop
AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge.
This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow.
Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required.
🛠️ What to Bring
Laptop: Fully charged and ready to go.
AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!)
🍕 Logistics & Perks
Food & Drink: Pizza and drinks provided!
Parking: Plenty of free spaces available on-site.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
Feel Good Friday: POWER BALLAD at the Gateway Film Center + SHAKE NO. 8!
Join us as we get together to see Paul Rudd in the latest comedy-drama-musical from John Carney, POWER BALLAD! The film follows a washed-up wedding singer, a fading boy band singer and a stolen hit song. Here’s a description, trailer and plan for this event:
DESCRIPTION: Rick, a washed-up wedding singer, and Danny, a fading boy band star, bond over music and a late-night jam session. When Danny turns Rick's song into a hit, Rick sets out to reclaim the recognition he believes he deserves. Power Ballad is written/directed by John Carney, the master of the modern musical and creative mind behind Once, Begin Again and Sing Street! It stars Paul Rudd, Nick Jonas, Peter McDonald, Marcella Plunkett, Havana Rose Liu and Jack Reynor.
BUZZ & ACCLAIM: The film premiered to rave reviews at this year’s Dublin International Film Festival where critics call it “a sure-fired crowd-pleaser” that “just might be the feel-good hit of the year!” Others say, “Paul Rudd delivers a career-best performance in this charmer” that’s both “hilarious and deeply moving." The film continues John Carney’s “long run of success with yet another charmer” and “a sharp, hopeful crowd-pleaser that strikes the right notes!”
SUMMER OF ICE CREAM, VOL 2: SHAKE NO. 8! Ranked the #1 Ice Cream Shop in Columbus, this is a perfect early stop on our Summer of Ice Cream! Their menu uses made-from-scratch recipes in an array of traditional, specialty and vegan shakes, hot cocoa, crepes, waffle sticks, specialty coffee & espresso, and more! Their specialty shakes are as delicious as they are over-the-top and they offer an extensive vegan menu! You can check out their full menu here: [https://www.shakeno8.com/menu.php](https://www.shakeno8.com/menu.php)
PLAN: Please purchase your ticket for the 6:45pm showing and we’ll meet in the upstairs lobby between 6:25 and 6:35pm! Advance ticket purchase is advised for this opening night showing! Once you have yours, please list your seat number in the Comments section of this event. We'll head to nearby Shake No. 8 immediately following the show!
Should be a fun one, Dan
