Tuckerton is a great show. Some of the best decoy displays are from Jode and Sean. I love looking at their birds in person. I do think the show has dwindled in recent years, and by that I'm talking about vendors. There doesn't seem to be as many vendors as there has in the past. In 1-2 hours you can have toured the whole show.
That being said, you definitely need to bring some cash. Lots of great stuff there. Diane and her decoy bags put Avery bags to shame. Tips hardware usually has a great selection of must-have supplies. Anchors, line, rigging etc. Like I said before Jode Hillman and Sean Sutton have some of the best artistic decoy carvings you'll find on the east coast and there are bunch of other great carvers who come with stacks full of decoys. Thats probably my favorite part, touring what the decoy carvers have brought. I'm never disappointed with those guys. I wish I could buy a pair of birds from every carver. A decent amount of duck boats too and you'll get some ideas about boat setups. Overall its probably the best show on the East coast second to the Easton Maryland show.
