GMARS Star Party!

June 28th & 29th

Summer will be in full swing for our next star party! Be prepared with cool clothing and plenty of water. Then again, it's GMARS! We'll keep you cool and hydrated if you're not able to! But watch out for snakes. You're on your own on that one!

GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning. Be sure to join us for the potluck Star-B-Q on Saturday afternoon (roughly 60-90 minutes before sun down). We provide the dogs, burgers and fixings. You provide a sidedish, dessert or beverages (if you want to)!
