I went through my Sports Collectors Digests and found this article in the January 31, 1976 issue, reprinted from the Bridgeport (Connecticut) Post. It's about card collector (and dealer, and SCD columnist) George Lyons and the hotel buying trips he regularly took with his wife and kids, the type of trip described by jsq earlier in this thread. I thought people might find this contemporary, first-hand account interesting. Based on my quick googling, it appears that Lyons is no longer with us, but I think Rob Lifson knew him back then when they were both dealers.
