I think most people with land (especially here at the DP) have thought about doing some gardening with it however, it can be a little bit intimidating to get started. Buying soil, picking weeds, and watering plants everyday can be more work than you want.
Instead of gardening I fenced my backyard area in and bought 8 chickens. They are so great! They keep the grass down so I never have to mow, they produce about 4-6 eggs per day, and they only require less than one hour of work from me every week.
