Posting this early because seemingly all Sundays in May are holidays or busy! I picked a shorter thriller that's hopefully a fast read/listen. [Columbus library link to book](https://cml.bibliocommons.com/v2/record/S105C3458940) Location: Grandview Cafe, *1455 W. 3rd Ave*, Columbus, OH 43212 [Menu](https://www.grandviewcafe.com/menu) Book summary: Daniel leads a rich life in the university town of Athens, Georgia. He's got a couple close friends, a steady paycheck working for a regional airline, and of course, for a few glorious days each Fall, college football tailgates. He considers himself to be a mostly lucky guy -- despite the fact that he's suffered from a debilitating disease since he was a small child, one that has left him unable to speak or to move without a wheelchair. Largely confined to his home, Daniel spends the hours he's not online communicating with irate air travelers observing his neighborhood from his front porch. One young woman passes by so frequently that spotting her out the window has almost become part of his daily routine. Until the day he's almost sure he sees her being kidnapped.

Join me for a small, mindful photography walk in nature. (**NOTE Time is 9:00 AM EST(Meetup is having technical Issue))** This is a slow, intentional gathering — not focused on fitness or perfect photography — but on simply pausing, observing, and being present. We’ll walk at a gentle pace, with moments of quiet, and a few light prompts to help you notice details you might normally miss. 📷 You don’t need any photography experience — a phone camera is enough. This is also not a business networking event. It’s a calm space to connect with nature and, if it feels natural, with like-minded people. 🌿 What to expect: • A slow-paced, relaxed walk • Moments of silence and observation • Simple reflection prompts 📍 Location: [ Red Trabue Nature Preserve] ⏱ Duration: \~60 minutes This is a small, initial gathering as I begin creating this space through WellGratiVibes — a blend of mindfulness, nature, and quiet connection. If this resonates with you, you’re welcome to join.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*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.

Let’s meet, wander the exhibits and open galleries, and enjoy an evening out in the Franklinton Arts District. (Nearby pay parking is available in the garage on McDowell, right around the corner from One Line Coffee, and, past it along the curb as McDowell dead ends.)

Join us as we get together to get together to help those in need at this CMG Gives Back event! We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “create a better world” by helping serve those in need. Here are complete details and our plan for this event: FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. For this event, our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces. PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:20am and wear closed-toe shoes and long pants.

On-site parking in the adjacent lot and street parking is available in the surrounding area. Below are some links / attachments with additional info/details: IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please try to update your RSVP no later than one week prior to the event. With few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. Our Partner Agency for this event is Lutheran Social Services! A huge THANK YOU to all of YOU for volunteering at this (and any of our previous) CMG Gives Back events! Should be another good/fun/meaningful time together, Dan
