I found a performance club in Fond Du Lac, which I think is reasonably near you. Even if you don't want to participate with that club, they'd be a good source of local info.
Rottweiler Breed Clubs
I'm across the river from Wisconsin and my local vet is looking forward to me picking up my pup because she never sees Rotties at her practice. It's good that she's open minded, but a bummer that I don't have a local vet who has experience with the breed.
