My second trip out, I was trying to get fuel. I had the GF hop out to spot, about the same time the gas station attendant came out to also spot.
The GF remembered the AC, the attendent would have run me right into his awning.
One thing I noticed is that if the overhang is low enough to hit, you probably won't be the first one to do it. Take a look next time you encounter one you're worried about, if its too low, it'll be all banged up or have paint transfers already.
