Next Star Party

September 2nd & 3rd

September is the first month we typically start to see summer temps coming down... but that's not usually until LATE September. So be prepared for the heat at our next GMARS star party! Visitors are always welcome to stay inside the house during the heat of the day to enjoy the MUCH cooler indoor temps.

GMARS star parties start on Friday afternoon/evening and go through Sunday morning. Be sure to join us Saturday evening for our Star-B-Q! Get more info by clicking the link below.
