Credit Island is not in Rockford. It's an island in the Mississippi River between Davenport, IA and Rock Island, IL. It has hosted 2 concerts (the first in 1978, my very first concert at age 14) and another in 1980 with Sammy Hagar, the Outlaws, J Geils, REO Speedwagon and Hot Moma Silver (according to Google).
