Bullshit, patrol will come get you wherever you are, if you can't describe where you are you shouldn't be riding there.
Wow, somebody started their day with some Hater-ade.
Your quote tells me you must ride a hill that has about 500 vertical feet and 10 acres of space. I take runs inbounds all the time, that I know for a fact, would be all but impossible to describe my location to a patroller. You ride in 3,000+ acres where every tree looks like the last one, and tell me you can always describe your location.
