Normal: Local Farmers Market Glut?

Farmers markets have been increasing across the country, resulting in fewer profits for the sellers in some locations.  I don't know if anyone keeps track of how well sellers are doing at the local farmers markets. It seems that with at least three markets -- downtown Bloomington on Saturdays, Uptown Normal on Tuesdays, and College Ave. on Saturdays -- we don't yet have too many markets. The local demand for fresh produce has probably kept up with if not outpaced the local farmers markets, which should keep the growers happy. In my opinion, if people are willing to go to those markets in some of the extreme weather conditions that we have around here, there must be a strong commitment to buying locally!
