Hey hey, this is the part where the GTNS comes in handy! of the 25 mountains I have been to, I think that Stratton, Sunday River, and Stowe are all tied for single largest jump. Longest & largest jump line however is a different story. I think the most large jumps I have seen in a row so far has been four major booters, and that was at Jay.
My home mountain (Gunstock) currently has the biggest hip I have ever seen anywhere though, if your into that.
