Converting lawns to productive gardens

Saw this New York Times article:

If your soil is good, fine. Rototill everything, add organic matter, and start. If your soil is not good, dump eight inches of loose fluffy soil on top, rake out, and plant. Its gotta be in sun and it's gotta have water source. It needs a fence, and a commitment to have someone follow through all the way or it will be a waste of time and money.

In the end though, it's totally worth it. I haven't gone to stop and shop in a week or more. Yeah, the dinners are somewhat repetitive but the squash is sweet and tasty and plentiful, and it won't be long before I'm chomping on cauliflower, tomatoes, okra, etc.
