So no zipper? Big freeway overpasses (bridges, but concrete ones, not underwear) do have one roof and two walls. The cars are a small price to pay. And sometimes they can get to you quite literally. But no bears! That’s important normally. Some bridges don’t even have rocky or artificially pointy floors floors. I don’t understand how rocky flooring helps us but it encourages us to find places with full wall coverage, that’s for sure.
