"Near" is quite a relative term. Things aren't quite as dense in that area as they are around Silverton/Ouray, but I think there's plenty to get to -- especially if folks don't mind an hour or so drive on a couple days to get to trailheads (a bit like driving to the base of Imogene Pass from Silverton).
I'm not sure what there is in terms of camping with hookups near Fairplay, but that would be closer to both Red Cone and Mosquito Pass, as well as Georgia Pass, Wheeler Lake, and a number of other trails.
Again, though, these things are all accessible with just a bit of driving. And barring an issue, I'm very much hoping to be trailering with y'all this year, which means I'm definitely hoping to have full hook-ups.
Really appreciate all you're doing to try and corral our unruly group, Knappster. It's thankless but welcome work.
