Cheap food: Ramen, Multi-Meat Hotdogs (Chic-urky 'n Pork), CARBS AND PROTEINS ARE YOUR FRIEND! You feel more full off them then a few 25cent brownies from a gas station.

Shelter: Car, Unlighted Parks, Salvation Army Housing (Free 1 night, 10$ a day there after, or 30$ a week).

Money: There are places in large city's that have "Day Laborers". I worked at once and there are alot of heavy alcoholics and drug users looking to score extra cash. Usually tho, if your clean and shelter at the Salv.Army, they'll put you first in line for work.

Done it once.. wasn't fun.
