That's right!
Hey if you do catch some oddballs I have no issue in looking them over for you. Just need good photos that show the fins, lateral scales, etc. Won't be able to photo tooth patches. for minnows, I would prefer that they be photographed from the side and in water. That way they extend their fins. From those photos I can try to give you an id. If not I am in contact with the gentleman that is currently revising the "Fishes of Missouri". If he is not swamped, I can usually get confirmation from him as well. Maybe if I get back up into Iowa, you might know a spot or two to catch orangespotted sunfish. I haven't had much luck with that species in Missouri and they are not native to Maryland.
