My first and only time in Plymouth included looking at this site (I really wanted to see Plymouth Rock, but when you travel with FIRSTers, things like “peek through the windows of the old Rumble site” are on the “Things to do while in Plymouth” list), and I can confirm this is the building.
Although I will give Elgin some credit: the person who took the pic (237’s faculty founder, Carll Pallokat) went to the 98 NJ regional, and if you glance at the picture quickly, it does look like the Rutgers Barn, the old NJ Regional site.
Grady was at work when this picture was released today. But it does bring back some memories.
It indeed was from Rumble at the Rock…though you are correct that the sign could be found anywhere that Plymouth North competed. You can tell its the rumble site because of the old style doors where the pit entrance was, plus the fact that there is a stage in the backround (the spot where Ron Partridge would announce from).
Great picture of one of the best robots of all time too…177’s magical claw…a thing of beauty.
