Carlisle Experience and buys

Tony hits the vendors as soon as the gates open and people are setting up. I saw him do it at MIR years ago. Thats how you find the best deals. Another way is to hit the vendors who are in the process of packing up their stuff.
Same deal at "hamfests." Back when I was more active, some of us would "go in" on a table, whether we sold anything or not. Got us in the door early
