Thrill Hill... bah, that's nothing. You Floridians are wusses. The real Thrill Hill, which is in Phenix City, Alabama, must be a 55 degree slope. You burn a gallon or two of gas going from bottom to top.
But actually, it would be inconceivable to skate on more than likely because it levels out every 70 yards or so... basically a sloped staircase of death.
Heh I've been through Phenix-City several times..I can't rightly recall as to where Thrill Hill is though, which end of town is it on?
