On Principles & Values: Town meetings in all 200 incorporated towns across Idaho

His aim was to hold hour-long, town hall-style meetings in each city, but some of the towns didn't have any halls. In those cases, the meetings took place in parks and once, in Placerville, under a picnic shelter. "We fit people in under there and just had a great town meeting," Crapo recalled.

Crapo finished his marathon of town meetings this past week in Wardner; 37 people crowded into the tiny City Hall to talk about the federal reserve, mining regulations and internet service in the Silver Valley, among other things.

The first meeting was in Moyie Springs in October 2014. The largest have drawn as many as 200 people; the smallest, as few as two. Most had at least a dozen. The smallest city was Warm River, which officially has a population of just three. "There were nine people there," Crapo said with a grin.
