Yeah I do remember the Tri-States shows, only went to a couple of them though, They were held at the Convention center also if memory serves?. I think the last Sabres show my Dad, one brother, one uncle and one cousin and I went to was in maybe '75 or '76. and it was back at the Colosieum, by that time most of us kids had moved from CO/Denver and/or had our own families, or were in the service.
By fall /winter of '72 I was living/working in Steamboat building condos and I never made it to our holiday gatherings.
