What's New


So this year, we’re doing something a little different. We will be one of many host locations for Camp Out for Cancer. It’s a fundraiser that raises money to send kids with cancer to camp. The Camp Trillium fundraiser will take place on October 14th, 2017. At GRR we encourage our members, their friends and family to take part and join our team. Participants will raise money and on Oct. 14th we will Camp Out at GRR. There will be movies, games, headlamp climbing, food, and a sleepover inside the gym! This is an event for all ages! So get some friends together and register at!
