Last night I got back from camping. A few days in the middle of nowhere were quite pleasant. Diving into bitterly cold water, poking around in the woods, and sitting by the campfire at night listening to the loons made for an awfully nice few days. S'mores don't hurt either.
It's hard to come back from this. Not exactly where I'd want to be in the middle of February, but in the summer it really doesn't get much better.
