Opposing fans never made up more than 500-1000 of the 10,000 plus that used to attend gopher hockey games. I attended enough to know. If anything, it's the exact opposite of what you wrote. Gopher fans loved seeing the UNDs, UMDs, SCSUs, etc. and showed up in droves to cheer against these rivals. That building used to rock when they scored against UND, their true fiercest rival.
