***FREE TOUR TICKET FOR ALL OF YOU WONDERFUL MEETUP MEMBERS*** Use Promo Code **MEETUP2025** to get your free ticket and route smart guide at [https://www.eventbrite.com/e/sol-in-columbus-oh-a-smart-guided-short-one-way-loop-bikeway-tour-tickets-769120860197](https://www.eventbrite.com/e/sol-in-columbus-oh-a-smart-guided-short-one-way-loop-bikeway-tour-tickets-769120860197) You can do the tour solo/with your favorite peeps, or try to generate a group ride of Meetup CycleNuts by RSVPing here and posting the day and time you are interested in others joining you. Either way, have fun on your memory-making adventure, and thank you for being a CycleNut! ### SOL in Columbus, OH \- A Smart\-guided Short One\-way Loop Bikeway Tour Short One-way Loop (SOL) in Columbus on bikeways. The smart-guided tour is mostly through scenic riverside parks with a quick downtown peek. All of that in 10 miles! 83% of the route is bikeway, and the rest is Google Maps designated "bicycle-friendly roads". This short ride passes through several beautiful riverside parks. Passing through downtown the route runs alongside Huntington Park baseball stadium, Nationwide Arena hockey stadium, near North Market (worth a stop if you enjoy markets with lots of tasty treats), within a few blocks of the state capitol, convention center, art museum, center of science and industry, several first-class hotels, and much more (see Points of Interest list below). Easily, anywhere along the way, the tour can be detoured to nearby points of interest. This smart-guided route comes with CycleNuts' 50% downhill guarantee. Sweating is optional. If your bike has gears, you might use them to climb in a few spots. All bikes are appropriate for this smart-guided tour (even a single-speed if you do not mind walking your bike up the spots mentioned). The route is shaded about 50% of the way. Sweating is optional - you set your pace, starting time, and touring agenda. Points of interest: COSI Scioto River North Market German Village The Scioto Mile Brewery District Huntington Park Nationwide Arena Columbus Union Station Arch Greater Columbus Convention Center **The Meetup plan = Show up, Rally with whoever else shows up, and Roll following the smart-guided instructions.** This is a smart guided tour route that can be ridden any day or time, solo or with others. It is only posted with a repeating set time and date with a tour leader to fit the Meetup format, and, more importantly, to encourage you to get out and ride when it is convenient for you. **If you are going to ride it and would like the company of others, then simply RSVP and post in the comments when it is that you are going to ride - date and time.** Take pictures/videos and share. Have fun! ***This is a repeating event on the calendar***\*, but the date and time do not necessarily need to be what is posted. **If you are interested in riding with a group, then simply RSVP and leave a message in the comment section** giving the date and time you would like others to join you. If you are interested in riding by yourself or with your private group of friends, then simply do it.\* ***The mission of this format is to create a catalog*** *of free group tour routes available for CycleNuts to ride as a group, or solo, in an area spanning several states. **The goal is to get people out cycling** either in groups or solo. **The vision is a cycling community with resources** available for bike tours, bike talk, and a format for lives experienced at the speed of bike.*

Contra dance Dec. 20 (First Unitarian Universalist Church)
Contra dance Dec. 20 (First Unitarian Universalist Church)
# **Band: Firefly Trace, caller Kenny Greer** Beginner lesson at 7:30, regular dancing begins at 8:00 **Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. Please bring your own refillable water bottle.

Recruiting Virtual Mental Health Group Leaders!
Recruiting Virtual Mental Health Group Leaders!
We are recruiting new group leaders for virtual men's groups! Our primary groups are outdoor movement groups, but we are launching virtual groups for the state of Ohio and beyond and the groups will move outside in the spring, creating room for men's groups, women's groups and coed groups all over the country. Read below to learn about our groups and click the links at the bottom to apply. ### **What is an Outdoor Empowerment Group?** Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being. Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment. ## **Why Join?** * **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance. * **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space. * **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection. ## **The Ideal Group Leader** The ideal group leader * Has a born-in passion for mental health, movement, connecting with nature and building community. * Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us. * Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind. * An ability to manage groups with high emotional intelligence and desire for human connection. * An ability to self-motivate and market/promote their group on Facebook and other social platforms. * Nature informed therapy or clinical therapists/psychologists a plus. ## **Our Impact** ![](https://images.squarespace-cdn.com/content/v1/64a6315db1eb8d081603d9ea/028252c7-347e-4196-8c79-b81d2a4db4bb/Mountaineering+Guide+Trifold+Brochure+in+Pink+White+Modern+Minimalist+Style+-+2.jpg) Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported: * A noticeable improvement in mental clarity and emotional well-being. * An increase in social connection and a sense of belonging. * Said they would return again. We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself. ### **Why Our Groups are Donation-Based** Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission! Every contribution helps us: * **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization. * **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year. By choosing to contribute, you’re not just leading an event—you’re helping build a mental health movement that supports long-term well-being and connection for all during a severe mental health epidemic. ## **Come Join Us!** We’d love to have you be part of this growing community of people prioritizing their mental health, movement, and connection. 🔹 **Visit Our Website to Learn More:** https://speakyourmind.men/joinusoutside 🔹 **Apply Here to Lead Your Own Group!** – https://form.jotform.com/taketimespeakyourmind/sym-group-leader-application 🔹 **Support the mission**: If you resonate with the mission and want to support, feel free to join a group before applying or donate to help us reach our goals to help more people!

Session Abstract **Data on Fire: A Hands-On Intro to Spark in Fabric** Curious about Apache Spark but not sure where to start? This hands-on session introduces you to Spark in Microsoft Fabric Notebooks—a powerful and accessible way to process and analyze big data using familiar tools in the Microsoft ecosystem. We’ll break down key Spark concepts like distributed computing, DataFrames, and lazy evaluation, then show how they come to life inside Fabric’s notebook experience. You’ll see practical demos that cover loading, transforming, and analyzing large datasets—while leveraging Fabric’s modern data stack, including OneLake, Dataflows, and Pipelines. You’ll also learn how to choose between Spark and pure Python notebooks in Fabric, based on execution needs, data integration, and use case fit. Whether you're a SQL pro, BI developer, or data engineer, this session will give you the tools and confidence to start using Spark in your own projects—no cluster management required. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

In-Person Event: The Answers to Depression & Anxiety
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.
