Mr Mud,
I'm doubtful that night rides at Skeggs are legal (are they anywhere?) but all the times I've done it...getting "caught" would be considered a toll. b'sides....they gotta catch me first. Ok...kidding but the point is, I do it but cautiously ie: don't park ON Skyline. The same group I ride with I also ride Demo and the UC campus during the winter...Skeggs can get UGLY. I'm trying to get back into some more regular rides (night or am) but with my preferred steed in the shop on a fork warranty....it will be another week at most.
Next week AM rides could be good.
