im not to sure how smart the wonderful bluegill are. they seem to bite on anything that hits the water around here. i will fish the dry flies when i see fish hitting the surface. the bass are also not to perticular as long as it makes some wakes and moves around.. its funny how many lures at the local tackle shop has hundreds that i think are made to appeal to the fisherman more then the fish. most fish ive caught if u look deep in there gullets they could have some revealing answers to what they are eating. some of the largest bass eat the smallest of bugs go figure.
