It’s interesting that the instructions want you to cup your hands around the nipple instead of just spraying yourself directly
The stuff at Truck Stops to make life on the road doable is really kind of interesting. The most interesting to me is "Idle Air," this set of gantries in the lot with tubes hanging down that mate with one of the side windows to provide AC, electric, TV, and internet without having the truck idle all night. It's an impressively large amount of infrastructure.
