Dumb question, but the law seems ambiguous here. It will be in AZ, for about a month. I'm in a parking lot, let's assume the business is open 24 hours (maybe a Walmart or a Waffle House), because I was once harangued by an officer for being at an Applebee's parking lot after closing. I will try to utilize Couchsurfing as much as possible too. I have an Anytime Fitness key so I could probably shower there. Is this illegal? Would renting a space at an RV park make more sense? I am in a cramped furriner car btw. Also, any tips in general on being semi-homeless would be nice.
