My last window quote was off by a solid three inches.

Wait, you think that sign is weird? I read a whole park ranger blog post about how squirrels in tourist spots are basically tiny criminals. They learn that backpacks mean food, and they will chew through fabric to get it. That sign is probably there because someone got their lunch stolen and complained.

That "very slanted campsite" is the exact reason I bring a small trowel. Sometimes you have to make your own flat spot, and it's never as good as finding a real one. I've spent a night sliding into the tent wall.
