Thanks everyone for the info on using a quilt. Makes perfect sense. I'm just getting to old to sleep on the ground anymore and the next adventure I take in Arkansas doesn't have a lot of flat/ remote sites for tent camping. So the hammock should solve 2 problems. Plus I got my mind set on the Clark anyway. I've never owned a mummy bag and wasn't sure of the need for one, so I'll buy a lightweight rectangular bag that I can use for a quilt. I'm not a winter camper so I'll use for mild 3 season etc.
