I'll have to say my home hill, Perfect North
has pleasantly surprised me with its 400' vert. Located in SE Indiana near the Cincinnati tri state area, they have some pretty nifty terrain, including ungroomed "natural" bumps and even some tree runs (although the trees are very widely spaced).
Due to great snowmaking, they managed to stay continuously open from early Dec, even when some more "northernly" hills had to close (or never open). This is my first year skiing there, and I've been very pleased.
PN compares very favorably to the other sub 500' hills I grew up skiing: Boston Mills & Brandywine in NE OH... which only have 240' vert!
P.S. I'd be willing to be that PN is also one of the only sub 500' hills that has had an avalanche
. The trail that had the slide is still extremely chunky on one side, almost glacial looking... crazy.
