Living in Tents, and by the Rules, Under a Bridge
New York Times, 7/30/09
Comments: My own preference, however, is not to be involved in any community. When you need a place to sleep, the best circumstance is to be away from all human contact in a place where no one can detect your presence. No "law" can give you better security than that!
In the US, people cluster together in homeless "camps" only because they have an emotional need for the community. The higher-functioning homeless just need a place to sleep, and this is best done in secrecy.
