Next Star Party

November 17th & 18th

Our next star party is back at GMARS. If you've never been to GMARS, now is a great time to visit. Temps may get a bit cool at night but you can stroll into the house and get some hot chocolate or coffee to warm up!

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!
