Well, if you're gonna go and there's no reconsidering or making shit work at home.. I'd at very least give the current season we're in some consideration when making this decision. January is the coldest month of the year, yanno? So, if I were making the same decisions I think I'd look at places closer to the equator. Florida being the closest. After that, it's more or less a tie between all the southern US states. By southern I mean the lower border of the entire country, so even southern California would be included. CA, AZ, NM, TX, LA, MS, AL, FL will be far warmer than the northern states.
As far as laying low and not being spotted, that's all pretty self explanatory right? Bright colors are obviously not ideal. Dark drab greys and black, brown blend in better with darkness. Or just get yourself a cowboy getup. For some reason cops don't seem to fuck with "cowboys" too much. I used to have a friend who did graffiti all over town. He'd just be strolling around on foot at 3am with a bag full of spray paint and markers bombing everything but when cops would pass him he'd just be some dude in a cowboy hat, a pair of shitkickers and some wranglers. They wouldn't even bat an eyelash at him. Apparently that's the "probably not a criminal, probably not committing any crimes" costume.
Good luck, be safe.
