Aww...don't let em razz ya too much Midnight. I once camped out in the Rockies at a site just west of Jasper Wyoming. It was cold, but nothing I couldn't handle, even considering I was raised in a sweltering hot cotton-patch Southern community. Idaho is much the same.
Wore some long-handles to bed, with a toboggan and wool socks. Stuck one light-weight sleeping bag inside a large, cold-weather bag. Tossed a couple of blankets on top for good measure. Slept like a log with only my nose exposed. No problem.
Aaaah....June!
