Bring a whiteboard or a laptop or a piece of paper. We will be solving 1 easy and 1 medium problem on LeetCode. We have no rules for being late or leaving early, you can be late and start from the second problem or do the first one and leave. The main idea is to work together on it, share thoughts and discuss a solution. For those who don't like the time pressure during the session, I will be posting problems in the comments for the session 1 day in advance.

Come out and get creative with PARR and the Georgetown Plein Air Watercolor group on Saturday as we paint the Sweet Lemon Kitchen! The light green building with its picnic tables and bright umbrellas makes a wonderful subject. There is a free parking lot across the street and public restrooms nearby. Hope to see you there!

This is a two day one night loop around lake Georgetown. This is a fairly flat 29 mile hike but some areas can be very rocky so hiking poles are recommended. This is a beginner friendly trip but the miles may be hard on some. This trip is highly recommended for those signed up for the Teton backpacking trip as a shakedown hike. We recommend to have a pack weighing around 30lbs to simulate an actual wilderness multi day trip. We will be starting at Jim Hogg park going counterclockwise. Making a stop at Tejas for lunch and to refill water. Then over to Sawyer or Cedar Hollow camp for the night. The next day we will continue our trek around stopping at Cedar breaks and the fishing platform for water if needed. This is a fairly easy hike but there are multiple bail out points if needed. Most people bail because they carry too much gear or get blisters. So wear good socks and shoes and pack light as you can. Food and water: You will need lunch for two days, 1 dinner and lots of snacks and electrolytes. Freeze dried backpacking food is recommended. Salty savory high calorie snacks as well. It could be cold and wet or 100 or both this time of year so stay hydrated. I don't trust the water out of the lakes or streams so we will be stopping at park TH’s to resupply at the faucets . I will have a filter for emergencies . Clothing: this will depend on the forecast but will most likely be cool in the mornings and warm in the afternoon so dressing in layers is recommended . Always have rain gear. Extra socks are recommended as well as a hat and Sun glasses . Treat your clothes with permethrin for ticks. Treat this like its an dry run for the Teton trip and you will get the most out of it, and most of all have fun! **Cancellation policy:** If you will not be able to make the hike, please be polite and change your RSVP to "not going" so that we don't wait for you at the trailhead. \# Event Waiver and Release of Liability\# By confirming your attendance (RSVP) to this event, you acknowledge and agree to the following terms: 1. **Assumption of Risk**: You voluntarily assume all risks associated with participation in this event, including but not limited to risks of bodily injury, property damage, or other losses that may occur during the event.

Please join us for a book discussion of Margo's Got Money Troubles by Rufi Thorpe About the Book: [Margo's Got Money Troubles](https://www.goodreads.com/book/show/199534613-margo-s-got-money-troubles?ref=rae_0) As the child of a Hooters waitress and an ex-pro wrestler, Margo Millet's always known she’d have to make it on her own. So she enrolls at her local junior college, even though she can’t imagine how she’ll ever make a living. She’s still figuring things out and never planned to have an affair with her English professor—and while the affair is brief, it isn’t brief enough to keep her from getting pregnant. Despite everyone’s advice, she decides to keep the baby, mostly out of naiveté and a yearning for something bigger. Now, at twenty, Margo is alone with an infant, unemployed, and on the verge of eviction. She needs a cash infusion—fast. When her estranged father, Jinx, shows up on her doorstep and asks to move in with her, she agrees in exchange for help with childcare. Then Margo begins to form a plan: she’ll start an OnlyFans as an experiment, and soon finds herself adapting some of Jinx’s advice from the world of wrestling. Like how to craft a compelling character and make your audience fall in love with you. Before she knows it, she’s turned it into a runaway success. Could this be the answer to all of Margo’s problems, or does internet fame come with too high a price? Blisteringly funny and filled with sharp insight, *Margo’s Got Money Troubles* is a tender tale starring an endearing young heroine who’s struggling to wrest money and power from a world that has little interest in giving it to her. It’s a playful and honest examination of the art of storytelling and controlling your own narrative, and an empowering portrait of coming into your own, both online and off.

Please join us in the peaceful space that is the Mind's Eye Plants Yoga Room for a deeply powerful afternoon of Reiki and connection. This Reiki Share is open to practitioners of all levels — whether you’ve just taken your first class or you’ve been practicing for years. We’ll gather in community, take turns on the table, and each receive Reiki from the group. It’s a beautiful chance to both practice your healing art and soak up some much-needed, incredibly powerful Reiki yourself, all while meeting and connecting with other practitioners. If you've never had Reiki given by multiple practitioners at once, this is a must try experience. Space is limited, so be sure to save your spot! Tea will be served. [Get Tickets Here - $25.00](https://www.mindseyeplants.com/event-details/february-reiki-share-for-practitioners)

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.
