I wasn't too impressed with this Farmer's Market - it really doesn't hold a candle to the Gilbert one on Sat nor the Ahwatukee one on Sundays.
Their selection is very, very limited and it's mostly crafters than farmers. Perhaps the farmers are busy getting ready for Sat and Sun events that it's just not worth attending this day's events. Oh well - it's a good concept and I think with time and with proper community demand, this one could grow to be bigger and offer a true farm selection because there are plenty of us that support it.
