Things to do while parked

You know those times when you travel and there is no rest area in sight but your bladder just doesn't care? Well, if you pull over and park beside one of these No Peeing signs, you'd have to just hold it. I'm not sure why some areas have these signs more abundantly than others...I suppose too many people stop there and the place is getting an odor..or maybe there are complaining neighbors within eyeshot that you may not even notice. In either case, if you're going to park and nap next to one of these be sure you go somewhere else to relieve your bladder or you might get a citation.
Sometimes...officers will run you off even for parking next to one of these, guess they don't trust that you're not going to step out at some point and take care of business.
