ive only tried it once, under the 422 bridge on ladue, and i only caught one crappie. i cant remember what i used but i think i was casting a white curly tail grub. i can think of a bunch of places in NE Ohio where this could be done, and was hoping fishermen who know how to do this could explain what tactics they use to catch crappies under causeway bridges. id like to take just a rod and a few lures, but what lures to take? (sizes, colors?) what kind of line is best? do you bump the bottom or just cast out and retrieve. any information would be helpful. i dont really have any crappie-specific tackle and would need to buy some.
