And now for on the road begging. Seriously, you made need this skill someday. (by Ben)

Step1 Get some cardboard and a sharpie
Step2 Write on the cardboard “Hungry(or hungry and traveling)”
Step3 Go to a busy place
Step4 Hold sign and look sad
Step5 Get fed

I'm not kidding this works. People are much more willing to give you food than money. In my experience you will always get fed. Feel free to be more creative with your sign. Like "food for thought" with a little smiley face and an exclamation point.
