The Atlanta Typewriter Meet has been held yearly since 2018 at the Southeastern Railway Museum in Duluth GA, an Atlanta suburb. The meet is held in the late January - early February timeframe (and sometimes in the summer) and is a great opportunity to meet new/old friends and buy, sell, trade and test drive some really cool typewriters. Best of all, you can spend a couple hours with like-minded typewriter aficionados who won't ask you "why don't you just use a computer, it's a lot faster."
It's sort of a mini-Herman's South (and it sometimes includes Herman!). For more on the Railway Museum, click here.
