Been there a few times to pick up brass, used to detour off I-70 just to do that and go over Loveland Pass. It was all fixed up last year or the year before, with the berms rebuilt and some asphalt put down. There's usually a bigass roll-off dumpster on-site too for trash. Shot there a few times too. It is a nice place.

Another nice public one, but kinda out in the toolies, is the CDOW range on US40 between Hot Sulphur Springs and Parschall, about halfway between Granby and Kremmling. Got some longer rifle ranges there. Shortly after you get out of the canyon it's on the right (north). Supposed to have a Habitat Stamp to shoot there, but I've never been checked.
