Keifer Park is the place to be tonight as Port Huron Parks and Recreation start up their annual “Rockin’ the Rivers” Free music concert series. The city's Toni George says the opening acts are all local bands. Headliners include tonight’s “Street Corner”, a Motown a cappella band. Then next week it's Your Generation featuring Fifty Amp Fuse. The following Thursday it's Jimmy Buffett tribute band Air Margaretville, and then it's Elton Rohn, an Elton John tribute band.
