Definitely. Weirdly enough there aren't really subsidies for vegetables, which is perfectly American. So competition actually isn't as punishing as you would expect for producing horticultural crops. And there is a big market for fresh farm grown produce. There are basically 3 models for independent gardening: farmer's market, CSA, and wholesale. IMO if you're going into it, you need to start a CSA. Farmer's markets are a time suck and I talked to a wholesale farmer who made 30k per year for basically managing a small labor army and business operation. I honestly couldn't believe it. I'd recommend "The Market Gardener" by Fortier as a book detailing the CSA approach. And "mini farming" was an interesting read too.
