Doesn't matter. There are many cities where it is legal or not legally enforced if illegal-- plenty of options. Look at Portland, Seattle, for example.

I lived in some woods in Portland for 3 weeks, applying for jobs daily from cafes, and visiting community centers for food & showers. Landed a corporate office job. Anyone who isn't disabled can do it. Claiming otherwise is a cop out.

The question is: How much do they want to succeed? How much are they willing to sacrifice comfort for success?

People take for granted their mental and physical fortitude. They give up far too easily.
