yeah dishing isnt THAT bad. i did it for 6 months. then i got a raise to cook. anyway thats beside the point.
what others said yardwork is where its at. people are lazy and will pay good money (usually) to have something done that they dont want to do - or are too busy to do.
also, you like golfing? ever thought of caddying? i did it for 2 summers when i was 14 and 15. if you get good at it you can make a lot of money especially with tips. i also liked it cause you could set your own hours, for the most part (at least the clubs i worked at let us). ALSO, if you like golfing, most clubs - at least the few i worked at - usually have a caddy morning or something, one morning once every couple of weeks or something like that, where caddys could get there a little earlier and play the course for free. its not that often but hey, you get to play on a really nice private golf course without being a member and for free.
