Population doesn't mean much to me. Girls hockey is as niche as it gets. I love it, but it's the honest truth. Like I mentioned above, all communities need to do a better job of recruiting girls to the sport.
In order to determine the viability of 3 programs in Fargo, would have to look at the youth club 15u down to 10u, check addresses and and determine which pipeline/school hockey girls are filtered into. In a 3 year snapshot (think soph-senior, but have to look back to basically 12u levels), if there aren't 18 girls it's going to be tough to pull off. Some of those girls will quit. Some of those girls will move to other schools. Some of those girls will leave the state.
Looks easy on the surface. There was A LOT of discussion in Bismarck on when, how and which schools to co-op.
