I've had Robert on the show a couple of times - once on episode 102 (http://foramusementonly.libsyn.com/episode-102-interview-with-robert-medl-6-11-15), then I went to visit he and Jeffrey in Ohio and did an interview there (episode 335 - http://foramusementonly.libsyn.com/episode-335-interview-with-jeffrey-lawton-and-robert-medl-1-29-16)!
Robert has a fantastic collection of many different playing Bally bingos, and is a fantastic guy to boot.
I'm looking forward to coming back that way and checking out your recent acquisitions!
...But you know, next, you'll need to get a United or 10.
