To extend J3's thought, have you priced prickly pears lately at an upscale supermarket?
Here's my small scale farming advice:
1. If you want to make money find a niche market crop you can grow and sell dearly.
2. You better enjoy hard work.
3. You will never get bored by running out of things to do.
4. Get a good, gutsy accountant who stays current on ag tax law.
5. Take every legal break you can - farming our land instead of just sitting on it saves us beau coup bucks every year in property taxes. In Ohio, this is called CAUV (Calculated Actual Use Value) - we get taxed as farmland, not as potential McMansion subdivision land.
