I was up on Tincup this past weekend with my kids, my brother, and his family. We came across a jeep above the last switchback on the Buena Vista side. It was *HARD* off camber off the trail - I think I could make out stains on the driver's seat! Yea, I know this thread is worthless without pics, but my card reader isn't working. In any case, I'd consider Tincup impassible to full size vehicles due to the snow on that last leg - about 200 yards just barely wide enough for the ATVs to get by. The jeep ended up off the side trying to sneak by - there was no way he was going to make it.
