Revenue will be the main topic Friday and Saturday at the Department of Natural Resources annual meeting in Brooklyn Center.  The DNR's Dennis Simon says without some additional funds they will be operating in the red starting July 1st of 2015.  Because of state law, the DNR cannot operate in the negative.  Simon says one option on the table is raising hunting and fishing licenses to help generate revenue.  He says the last increase was back in 2001.  Simon says the fees are set by the legislature.
