You know, I heard this a couple of years ago but know many who've ridden there without a license.
BTW, and probably unique to me... while I felt the Star School was excellent I didn't really learn that much. It mostly reinforced what I'd already read in books. I gained the most from the two days of practice with instructors following, and two fast laps around the track as pillion with Jason Pridmore piloting.
... one is hit in the head with the realization the bike is far more capable than we let it be.
