Straw Bale Gardening

The other day, at Tyler's baseball game, I was talking to one of the grandmothers there who introduced me to straw bale gardening.  I had never heard of this method, but it is so simple and easy that I figured I would give it a shot.  The straw bales are really cheap.  The idea is, you water them for ten days and then you can plant veggies in them.  I bought two bales at Ace Hardware for like 3 bucks each.  This is an especially awesome method for people who don't want to mess with soil,tilling, weeding and all that.  I'm excited to see if I can get this to work.
