Upon further review…
It took a bit of looking, but I found my 1971 tour schedule card. On the back I wrote our record against every major corps we faced that year. That was in 1971, right after we got home, so no time for the memory to get fuzzy. We were 3-2 against the Cavies, so it looks like you were right. Here’s the rest: Troopers 15-2 (1 by penalty), Madison 11-1, Blue Stars 12-0, Kingsmen 2-2, 27th 2-2, Blue Rock 2-1, Garfield 2-0, and Boston 4-0. Most importantly, we placed 1st at the VFW finals which made us that year’s champion!
