That's the really great thing about memories - they are only triggered by physical things, not contained by them. I've got plenty of fond memories of Grandpa, and plenty of things from him to remember him by, so I'm ok with letting this one go. Nobody living has a memory of this buck that I could find, and it might be a dead head for all I know. Just know I was told it was from Pend orielle county as a kid.
I was thinking a 130-140 class as well, but I am usually off by quite a bit. It's a cool rack, had a nontypical point on the inside of the passenger side that was broken off.
