Another piece of the RiverFest 2012 entertainment puzzle is in place. Kerri Griffin of the Chamber of Gadsden and Etowah County confirmed Thursday that 80's rockers Skid Row will open RiverFest's opening night on Friday, June 8th. They'll be followed by former Foreigner lead singer Lou Gramm and the band Fuel. So far, the Saturday night lineup consists of the Oak Ridge Boys and Jamey Johnson. Tickets are expected to go on sale next month.
