I'll let any free-stater (or wannabe) crash on my futon if they'd like or if they're in the area.
Rules for acceptance would be:
If I'm friends with you on facebook and have some level of trust, you could stay for awhile rent free, minimal mooching of food/car rides/etc.
If I am unsure about you I'd request collateral to keep you from stealing my shit and running. Allowing me to lock an envelope with your social security card might work, or some other valuable item you'd hesitate to leave behind.
If you call yourself "pubella" or "anarchojesse". Dont bother coming by
