UTICA-ROME -- Country music star Josh Thompson will know Central New York fairly well by mid-June: a week before he's scheduled to appear at the State Fairgrounds in Syracuse, he'll be performing at Frogfest for Utica-Rome country station Big Frog 104 (WFRG). Out of 24 years of Frogfests, this will be the second-ever to charge admission, a change which started last year, as the station added a rodeo to the concert.
