Went to GER last November and wheeled for 3 days and had a blast. Currently sitting 7 miles s from Windrock and getting ready for breakfast and day two of wheelin.
We had fun on our day trip. We hit 4 of the "black trails" but the park is very tame if you're locked and on tons and 40s. We dropped off into the Cove and hit some much better obstacles. When we go back we will hit the other black trails and drop into a different section of the cove.
I have a little bit of insulation (2" inch foam boards with foil backing on both sides) left to do but I am mostly done with everything. 24x55x12 building and the concrete pad is 4000 psi fibercrete and 5-6 inches everywhere except where the lit is and it is 8-19 inches.
