I live in Michigan and both those schools have sent me "personal invites" too. They are running a few camps together and I beleive they are just sending letters out to people who have attended showcases/camps in the region. The camp is a money maker, like most, but that dosent mean it is bad, they will still look for good players. That is about all I know about them, i dont really know if they are good/bad but i would think it would be some good instruction considering it is coming from the coaches.
