That's obvious and I didn't just fall off the turnip truck today. It's not even a concern for me as I don't drink, smoke or use drugs... not as a moralism bumpersticker thing, just not a fan and impaired judgement isn't wise.

There are a couple of these jackasses living in vans whom live like animals, get high and generally make things harder for everyone else, but they don't last long. They're in a minority because the majority are retired guys. There are some retired gals, some younger mostly guys but very few female vehicle dwellers generally.
