The AI studs frequently have schools scattered aorund the country. Most of the 3-4 day schools are only a couple of hours each day. I think it's Graham school and I'm sure there are others that are pretty much a total immersion type. You spend all day every day with some aspect of breeding.
Here is the link for the Graham School, they have been around a long time and I think they have a pretty good reputation. Garnett, KS is where they are located. I don't think they are affiliated with any of the breed services , if it matters.
