So we carried a paper cup, and had a chuckle, and fortunately, no rider hurt himself where I was stumpsitting. I made some photos instead. If you were present, I permit you to download it, copy it and do with it whatever you please, provided you give me some nice credit to it;-).
Riders were going uphill on singletrails and a steep fireroad. I was sitting in a bend where the course went uphill.
