Found this link on another site of an antique phone show near me in Nebraska. It is located in an old AT&T Underground Coax site that was used during the Cold War w/ their transcontinental cable system. A few pics on the site as well.

I'm not going to be here on that date, but really sounds interesting. I've been in the one in Chadron, which is now private residential property. Thanks for the link.
those shows look like fun but none are near me. closest thing would be the Hamvention and I bet they might have phone stuff for sale/swap.
Pretty cool. But to far for me
Hamvention does have quite a bit of telephone stuff, but the guys selling there think it gold. I usually bought cellular gear. One year I had the entire back seat of the airplane filled right to the ceiling. We always had to get a hotel reservation 1 year in advance. In order to get parked real close, my wife and I would drive to the site at 2:00AM, and sleep in the car until the gates opened. I think about 8:00AM. Great fun, and so many people.
I have a friend who goes to the Nebraska show. Always a fun time he told me. He brought back some equipment for the Antique Telephone Museum that he (and now myself) is a member of.
