I've only been 'urban farming' (ok, gardening) for about 3 years now. Two years ago I had so many cherry tomatoes I sun fried them and then swore I wouldn't grow them again. Last year I had green tomatoes due to bad weather and this year I haven't even planted any yet.
Still, this is what gardening is all about. One year to get too many zucchini (ok, every year) and the next year you actually grow an eggplant. I love the surprise. It's way better than just opening the refrigerator door.
