Next Star Party

November 4th thru 7th

The Club's next official star party is at Nightfall! Join us at the Palm Canyon Hotel & RV Resort in Borrego Springs for one of the best, if not the best, star parties ever anywhere! Visit www.nightfallstarparty.com for all the information you can possibly need.

It's not certain yet whether or not GMARS will be open the same weekend as most keyholders will likely be attending Nightfall. Stay tuned to this space for any updates.
