The gun shows that the wife and I have been to had very little to NONE for fishing stuff. Don't know about this Show in Colorado Springs, but a lot of times, ads can be very deceiving as to what they have to sell.
After Kmart sold off lots of fishing stuff from closing stores, I saw some fishing stuff for sale at local gun shows.
You might get lucky and find the Eagle Claw sale items at a local show.
I'd just go save the time and go fishing.
