Gshad just wreak of fishiness! I mean stink! But I guess that is why they make such great catfish bait. Castnet a few fresh gshad and let them sit in a likely catfish hole in the Potomac River and you're arms will be hurting by the end of your fishing trip from having caught so many 20 plus pound blue cats.
