The free NASP safety course (can't vouch for others) is the very same MSF Basic Rider Course you will take in the civilian world for a few hundred clams. It is taught by the same civilian instructors that teach the course at P'Cola Harley, and others. Also, the course is free for spouses.
They do, indeed, offer the MSF advanced courses, but not as often as the BRC. Call the safety office for more info.
