I'd seen a few people at the locks this weekend watching them too. There are no shortage of the big fellas there that's 4-sure.. They give you quite the scrap when they take you crappie offerings a few weeks from now..
Ever watch the guys on the WFN catching carp with those long poles?? That pond they catch them in must get pretty messy after all the junk they fling into it with their sling-shots.. Guess that's their way of chumming the spot..
