Another problem facing the vehicle denizen is cops.  There's some health code that says it's illegal to sleep in a vehicle, and from time to time it's enforced, and so in the middle of your nice sleep comes a violent cop knock in the night.   I talked to one guy living in a massive RV, and he gets cop knocks all the time because he parks in a spot that cops don't want people parking.   But his strategy is to wait the cop out, since if the cop can't see him behind the blackout curtains, he can't give him a ticket.  The problem is that cops know that moisture on windows means a person is inside, so they will bang hard, which is shockingly loud when you've been sleeping in your quiet vehicle for a few hours.  It's like being inside a drum.  But this guy said he just waits until they go away.  The funniest part:  he wants to install plexiglass shields over the windows so the cops don't break the glass when they bang. 

If the cops catch you they usually only give you a warning after which you can groggily drive away, but sometimes they'll give you a citation, which is a pain the rump as you have to go to court.

But in San Francisco and much of the west coast they rarely enforce that damn law, so people are for the most part free to live in crazy vehicles like this one.

"Welcome Home" and "We Love You" are slogans of the "Rainbow Family" (Rainbow Gathering stuff).  The hard core "Rainbow" types liken themselves to an indian tribe travelling the country and from time to time convening in national parks.  (Click here for some words I wrote at a Rainbow Gathering).
