Don't expect to re-stock all of your tackle needs. It is a good way to deal with the cabin fever though. I do attend it every year to just browse. One year I did well on sinkers. I checked out one of the tables outside and in the coffee can are 6ozs bank sinkers that was sold for 3 for a buck. I went around tables again and came back and saw the changed sign that said 4 for $1.00 for the 6oz bank sinkers. We'll, I cleaned it all up. In fact, I still have plenty left.
I'm not sure what you're looking for but there's plenty of fishig rods (lots of boat, not that many heavers), reels, FW lures and lots of boat stuff. I wish they have more SW lures though.
Anyway, hope that helps.
