I used to live in the Boston area as a kid and dad used to take me to loads of ham radio swap meets in the city. I loved rummaging around the stuff and finding cool things to try to use with my Commodore 64 (even in the 80s, ham swap fest's had a lot of computer gear proliferating) I really miss the format but I just haven't seen them around for years (decades?) at least in my part of the world...
