The Development Authority of Dawson County last week released numbers on tax revenue for the county for the month of May, and stated that May 2017 sales tax collections were the highest ever recorded for any month of May. "May was an extremely good month for Dawson County businesses," said Charlie Auvermann, executive director of the development authority, in a July 6 press release. "We hope it is a sign of the start of a very good summer."
