Here is a brief summary of what some local people in two Iowa communities think about their co-ops. The authors recongize that the sample of Iowa farmers, businessmen, and civic leaders is far too small to be statistically accurate. But we think you will be interested in the observations. A more complete study, based on a state-wide sample, is now under way.
