We were the Broncos.
DS is a Fighting Farmer - I'll never get over that one, especially since they were our arch rivals when I was in HS. The mascot has a big scary head and wears overalls and a farmer hat. They hold their fingers up in a position that looks like an "L" (actually looks like the sign for "loser").
My sister recently moved to a town where the mascot is the Pretzels - Huh?
