I attended the tournament in the spring of 1988, before heading to TCU. I had friends at Edina HS, which is a hated suburban school (wealthy) but highly successful and accomplished. I went with them and even did the green face paint.
Their opponent was Warroad, a small town school from far northern Minnesota. Warroad is known as hockeytown USA and was home to the Christian brothers who helped win 1960 Olympic gold, the Marvin family with multiple standout players (including Gigi who played for the last three women's Olympic teams), and others. Another very successful HS program but completely different from Edina.
The arena was packed. First goal goes to Edina and the two sections filled with Edina fans go nuts. Second goal goes to Warroad, and the rest of the entire arena goes crazy. No surprise as to who the crowd favorite was.
I was probably lucky to get out of there when Edina won.
