The farmers market in Santa Fe, New Mexico is really a fine one for a town of only 65,000 souls (plus many summer visitors). I am not sure who the most outstanding producers are, but there is organic beef and lamb as well as great produce. There must be a great master chili grower as you say!
If this idea strikes you I could approach the farmer I work for to see about his contacts as he sells there on Tues. and Sat. market days. Would this likely be for PBS? Best, Tom Schley
