True - I was thinking about their girls basketball, which is 3A, but forgot girls have the extra class in some of those sports.Estherville is 2A in football, basketball, baseball, golf, track, etc. Same size as current Twin Lakes member Southeast Valley.
What they did historically when population centers were different doesn't mean anything. Once upon a time, Audubon played Emmetsburg in the 3A football title game. Now one is in 8-man and the other is in 1A.
While football is not subject to conferences, it still is strange to have schools with 2A football teams in leagues with 8 man teams. And in the case of TLC, some of these would be in a smaller division of 8 man if split.
