I managed to climb cable hill years ago on 36" bias IROKs. It was completely bone dry that weekend (the whole park was a damn dust bowl), but I still climbed it. Those are some huge steps. Same weekend Bassler did his backflip in the Ultra4 car. lol
I'd like to get over Pony Hill. I've made it to the big hole in the middle, but never past that. It's a crap shoot every trip if it'll even be in shape to get tires on it.
I've never given CreamPuff a serious try, but I'd put that in the list.
Little Jager rounds out mine. That's one we always seem to get to the first night we are in town and I don't really try all that hard to make it.
