under bridges
Thought sleeping under an overpass on a sandy bank of a creek was a good idea in Kansas one night.
The wind picked up at 2am and pulled all the stakes out of my tent.
I was walking around with a flash light, naked, trying to find my tent stakes but gave up. It was too windy anyway. Just layed there until the sun came up with the tent laying on my face.
If you sleep under bridges sometiimes they turn into wind tunnels. Beware.
