Out of all the times my grandpa took me fishing as a kid, I remember the bait catching more than the fish caught. We alway caught our own bait, dig worms, catch hoppers and little frogs, seine a few crawdad and minnows, scour riffles and grab hellgramites by hand (takes some skill). Great times and really learned a lot about nature. Oh and occasionally find a big wasp nest to use the pupa for bait.
