Steve - funny you mentioned the potato. My dad use to eat raw potatoes every day. I always thought it was gross until i decided to try it one day. It really isn't that bad. In fact I'm sure a person could get addicted to them.
I'm really trying to get to 100% raw but it's not easy. I am beginning to love apples, strawberries and bananas. My biggest problem has been getting enough calories. (never had that problem before :)) One has to eat A LOT of raw food to get enough calories.
