I usually hit 4 to 5 per year. Generally find a deal or two. Get an idea of what prices are ( new versus used). I have found some real bargains.
I enjoy a good swap meet, also. Trouble is, it is getting hard to find a good one. At least around here. All the good old true vintage tin seems to be long ago snapped up. There is one, relatively close to me, each summer, in Evansville, Indiana. It never disappoints. About the size of a football field and a half. Alot of gas station memorabilia, along with everything else. Steve.
