After I described my crazy visitor from last night to a former-criminal friend of mine, he made a pretty good point. Every fall up here, when the weather starts to get cold, Natives will intentionally do something slightly crazy to get arrested and sent away to a halfway house for the winter so they can have a nice place to stay for free when it's cold outside. This makes sense, considering the guy was fairly well dressed and had a backpack on. He must have packed up a few things, dropped some acid and set out to get arrested.
