You can kind of point that way around every metro in Iowa right now and it's only going to get worse.
CR/Marion--North Linn
Iowa City--Clear Creek Amana and Solon
Waterloo/CF--Dike-New Hartford (Denver and Jesup are coming)
Dubuque--Western Dubuque (though they're 4A now) and Cascade
The Iowa City reference may be right but the others just simply aren’t.
DNH benefits from having families locate there that work in CF but want a smaller school, but I don’t know of many/any that open-enroll from CF to DNH. Denver is the same exact story, Jesup is just way off base for this example.
No one drives from CR to Coggon to open enroll. Coggon is way more rural farm town than it is CR suburb.
Same story for Epworth. Wahlert recruiting Dubuque, then playing a 3A schedule is a better example of recruiting issues than anything Western Dubuque does. Plus Western Dubuque has been 4A off and on anyway over the last decade.
