OK, how about Kelly Dahl or Golden Gate Canyon - Reverend's Ridge Campground?.
Kenosha Pass has a lot of hammock friendly sites.
Burning Bear by Grant is good.
Rolling Creek Trailhead that separates Segment 3 and 4 of the Colorado Trail has many excellent sites just a short walk south.
Colorado has got some places.

That said, if others would prefer to keep it lower and warmer, I'm happy with that too.
