I don't know how it is in CA but I went to a college in mid-Missouri. Every weekend a few buddies and I would go into the woods and hunt small game. It's amazing how many times we came back empty handed only to find the game we spend all day trying to get running across a busy intersection in an urban area. Cities are full of squirrels and such. I don't have any doubt I would be able to snare enough food even in an urban setting.
