One day Michael Richter and I slowed down and asked one vendor who was a producer in picking what we all search for and asked if he had "slot cards" and his response was "Yeah. I have thousands. Didn't know you guys were into them." He said that he will load up his trunk with them next month... and he sure did -- thousands of them, just as he said. The only problem was he did not have one "slot card" to show us... and later explained to us that he hits midweek fleas such as Webster on a Monday and a Tuesday flea out near the west coast (FL) with completely different inventory and though he does rotate, he normally sticks with what works best for him in West Palm. We never saw another "slot car" on display from him, since.
