not speaking to this specific post, but my preferences: i've only recruited at d2/3, and my favorite area is the midwest. i believe missouri/indiana/illinois provides for good local recruits, access to a great deal of late diamonds in the rough at some moderate distance. it really just depends on the competition in the world, but i think the west is the worst. not high population density anywhere except LA, so you're relying SOLELY on how good the players are in that area. ofc NY/east coast is good too, but again, depends on the talent-- when i've had d2 schools there, i find the players im looking for are much more tampered by d1 schools.
i just won a title in colorado, but i REALLY hate recruiting there. i mostly recruit nationwide with my d2 school there.
