You probably shouldn't do tricks down hills, but whatever. Went down some hills yesterday, only went like 30 or a little faster, but fun stuff. IB SD2 talk about Point X hill, that's not a hill, that's a mountain. SF dudes, let's hear it, you guys got some real hills.
Travis and I bombed this hill in Newf two summers ago when I was there, it was rad.
One street over from me is basically a huge hill that ends you up in the projects behind my house, and it has these big smooth speedbumps that you can basically use as pump bumps if you get going fast enough. Loads of fun.
If you cali slidered down a hill in SF you would need to bolt a piece of steel to your heel first if you wanted to keep your shoes.
I was also thinking if you could do one so your heel drags on one of those trolly tracks that are metal so you could slider forever
