Are there great opportunities to buy land in the San Luis and start an organic farm?

Do it!

That's all I have to say on the matter. :)

Overall this would be a great place to start, but it takes time to become 'organic' certified in the state of Colorado. There must be no farms or ranches within five miles in any direction that use or have used pesticides or other chemicals for the prior five years. I only know this because I used to know an organic peach farmer on the western slope. :)

I agree Kristin, what a cool thing to do for a living!
