I was in a total eclipse in Sidney MT during my senior year in HS.
Pretty cool. We all went outside to experience it. If I remember right, it was about 10:30 AM give or take, went dark as hell for a few minutes.
Even some pictures of it in the ol' school yearbook of 1979.
In 1979 I was a senior in HS as well living in Bozeman MT. I remember watching the total eclipse.
