I would totally do that if I lived on a smaller lot in town. There are actually quite a few front yard veggie gardens sprouting up in the trendier part of Boise. Our septic tank is the the front of the house though, so we're sort of tied down to keeping a small patch of grass over it. However, we're slowly reducing our amount of useless, wasteful lawn - front yard will eventually be xeriscaped, including low-water, no mow grass where we need it, and native shrubs and grasses over the rest of it. About half of the backyard has already been converted to an edible garden, and the side yard will be turned into a pumpkin patch this spring. My philosophy is: if I have to water it, I should be able to eat it.
