The freegan lifestyle is not that uncommon jillianfan. The amount of perfectly good food that grocery stores throw away is criminal. I dont see why they cant hook up with local food banks.
I actually was going to come back in here to suggest not dumpster diving but when fruit is in season keep an eye out for fruit trees and bushes. Dont take off someone's property, but a lot of times either they will let you pick it and take it away or let you pick it for a share. My friend has about 25 cherry trees on her property and she doesnt want to get in to selling fruit but you can pick all you want for free if you give her 25% of what you pick for her family. There are berry bushes lining public roadways but becareful of those because some areas spray weedkiller and pesticides. Apple trees around here are often unpicked
