Seagull was the most crazy non fish animal I've caught with a rod.
Strangest place to fish was in a swiming pool at a sportsmans show.
strangest fish catch or unexpected catch was a red fin pickerel from Geneva swamps. It wasn't a baby pike either. I sent a pic to the PFBC to confirm. Also a quillkback carpsucker from the Beaver River. They are not super rare, but I've never seen one prior to catching it.
My wife caught a snake on a minnow & I've had crayfish hold onto my bait all the way up, same with blue crabs in the ocean.
