Let’s explore an upscale dining experience that blends West African tradition with modern culinary innovation. We are heading to **Elmina** in Shaw, from Top Chef finalist and Food Network personality Eric Adjepong, known for bringing modern Ghanaian cuisine into a refined dining setting.
**FOOD**: Elmina blends traditional West African flavors with modern technique, with a menu that highlights depth, spice, and layered composition. Dishes frequently called out include the jollof duck pot and egusi stew dumplings, both reworking classic Ghanaian staples into more refined presentations. You will also find grilled meats with suya-style seasoning, seafood dishes with balanced heat and acidity, and rotating plates that reflect regional influences.
The menu leans bold and savory, with options across meat, seafood, and some vegetarian-friendly selections. Cocktails often incorporate tropical and spice-forward elements that align closely with the cuisine.
Most members should expect total spend to land roughly in the 55 to 85 dollar range, depending on beverage participation.

House Rules -
1. Starting Play: Each point begins with both teams lining up on the front of opposite end zone lines. The defense throws ("pulls") the disc to the offense.
2. Scoring: Each time the offense catches a pass in the defense's end zone, the offense scores a point. The teams switch direction after every goal, and the next point begins with a new pull by the team that just scored.
3. Movement of the Disc: The disc may be advanced in any direction by completing a pass to a teammate. Players may not run with the disc. The person with the disc ("thrower") has ten seconds to throw the disc. The defender guarding the thrower ("marker") counts out the stall count.
4. Change of Possession: When a pass is not completed (e.g. out of bounds, drop, block, interception, stalled), the defense immediately takes possession of the disc and becomes the offense.
5. Substitutions: Players not in the game may replace players in the game after a score and during an injury timeout. (Modified depending on the number of the attendees)
6. Non-contact: Players must attempt to avoid physical contact during play. Picks and screens are also prohibited.
7. Fouls: When a player initiates contact that affects the play, a foul occurs. When a foul causes a player to lose possession, the play resumes as if the possession was retained. If the player that the foul was called against disagrees with the foul call, the play is redone.
8. Self-Officiating: Players are responsible for their own foul and line calls. The host will also step in if it is needed.
Please message the event host for any questions or concerns.

Spirit Island --> Punchbowl Social, 1st Floor (Ballson, VA)
***Spirit Island*** is a complex and thematic cooperative game about defending your island home from colonizing Invaders. Players are different spirits of the land, each with its own unique elemental powers. Every turn, players simultaneously choose which of their power cards to play, paying energy to do so. Using combinations of power cards that match a spirit's elemental affinities can grant free bonus effects. Faster powers take effect immediately, before the Invaders spread and ravage, but other magics are slower, requiring forethought and planning to use effectively. In the Spirit phase, spirits gain energy, and choose how / whether to Grow: to reclaim used power cards, to seek for new power, or to spread presence into new areas of the island.--

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!”

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.

**Abstract**
Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod.
