LOL - I have had that bumber sticker on 3 cars.
Going to Sturgis from Minnesota along I-90 it seemd that the magazines noted on the billboards got less reputable as you got closer to Wall.
Just over the Minnesota border it would be "Wall Drug as seen in Time Magazine" - half way accross South Dakota you would see "Wall Drug as seen in People Magazine" - 50 miles out of Wall - "Wall Drug as seen in the National Enquirer"
Back to the topic at hand
Dad was a hockey coach, and to get game films in 1969 or '70 the school got a
reel to reel video tape recorder for the athletic department. Used 1/2 inch tape, a small (for it's day) camera, and it was, of course, only black and white.
Very high tech for the time
