I know that there is a barn near here that regularly used to lease out their indoor arena to the bmx people. They would haul dirt in for the weekends ect then take it back out. Is something similar to this possibly what is going on?
The little skate park is now gone from the indoor since the snow is now gone from our area. But the day I went to check, it was still there. Also, I was actually mad that it was still there because Murray had a freak out by snow falling off the roof at the time. I was walking him from the ground, but I could have easily fell over and have him step on me. Thankfully, I kept my cool, got on him, walked around inside before riding outside that day.
