Hike Scioto Audubon Trail with optional lunch at Nocterra
**No, the hike is not canceled! We will cut it short if need be but I’m confident we can do this! One of the last times (Feb.) it was 12 degrees and three of us showed up and had a fantastic time. I’m confident this hike will be the same :). Just bring water!**
**Hike the Scioto Audubon trail. All paved and flat!**
**Plan on 3-4 miles. Hike at your own pace, no one left behind.**
**Lunch after at Nocterra for those who wish.**

CAPA Summer Movie: PRETTY WOMAN at the Ohio Theatre!
Join us as we get together for a CAPA Summer Movie event to see the romantic, funny, heartwarming, feel-good classic, PRETTY WOMAN! Julia Roberts and Richard Gere star in this modern-day fairy-tale romance! Here’s a description, trailer and plan for this event:
DESCRIPTION: A wealthy corporate raider hires a Hollywood escort as his date for a week of high-society business events. But what starts as a business transaction blossoms into genuine love, challenging both of their lives and leading to an unexpected romance. The film is directed by Garry Marshall and stars Richard Gere, Julia Roberts, Héctor Elizondo, Ralph Bellamy (in his final performance), Laura San Giacomo and Jason Alexander.

BUZZ & ACCLAIM: A huge box office hit at the time of its release, PRETTY WOMAN has since gone on to become a modern-day classic! The film catapulted Julia Roberts to superstardom and earned her a Golden Globe for Best Actress and her first Oscar nomination! Critics praise Julia Roberts’ star-making performance, the undeniable chemistry between her and Richard Gere, and its warm, funny feel-good story about kindness, self-worth and transformation! The film’s “intelligence and wit,” “first-class performances” and “sharp, funny script” have made Pretty Woman a classic and truly “something special!”
THE OHIO THEATRE: The Ohio Theatre is located at 39 E. State Street, between 3rd and High Streets, across the street from the Ohio Statehouse. From classical music to modern dance, yearly family traditions to hot concerts, the world’s best artists come to the 2,791-seat, historic Ohio Theatre. The breathtaking details (including the 21-foot-high chandelier!) of its opulent, Spanish-Baroque architecture make any night at the Ohio Theater an event to remember!
PRE-SHOW ENTERTAINMENT: Now celebrating his 33rd year as featured organist for the CAPA Summer Movie Series, Clark Wilson will again provide pre-show entertainment at the keyboards and controls of the Ohio Theatre’s treasured “Mighty Morton” theatre organ 30 minutes prior to each screening.
PARKING: Parking is available at Columbus Commons Parking Garage off 3rd or Rich Streets or in Statehouse Parking Garage off 3rd Street. You can find out more about parking in Downtown Columbus by visiting the Downtown Columbus website.

Walk & Talk About Life's Big Questions
[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations.
If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!).
**HOW IT WORKS**
**Step 1: Bring a topic**
Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event.
**Step 2: Circle up & share**
We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds.
**Step 3: Walk, talk & float**
We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!"
**Step 4: Feel more alive**
Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times.
*For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)*
**HOW TO BRING A GREAT TOPIC**
A great topic = something you're genuinely curious about.
Recent topics include:
* "What are you passionate about right now?"
* "What makes a good friend?"
* "What's a belief you used to hold that you've completely changed?"
* "How do you want to be remembered?"
* "What would you do if money wasn't a factor?"
Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter.
**WHAT TO EXPECT**
This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.*
But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here.
**FAQ**
* Wear casual athletic attire and sneakers. It's a long walk!
* We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space.
* We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space.
* Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know.
* Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic!
**LOGISTICS**
* If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event.
* This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs.
* Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details.
* If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋
**IF YOU WANT TO GO DEEPER...**
[The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up.
* This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

CBusData - Highlights and Hidden Gems in SQL Server 2025
Highlights and Hidden Gems in SQL Server 2025
With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session!
Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
