Thanks Linden and Carl. You raise some interesting points.
Fortunately, he has no interest in motorcycles/motorsport (yet). Honestly I don't want him anywhere near road bikes. (I am selling mine because it is too dangerous for me). Ive suggested go karting but he wasn't excited by that at all. He is eligible for his Ps but hasnt bothered getting them yet. This suits me fine. Maybe i need to force him to go go karting. That is a good way to get lots of track time and learn the fundamentals of driving a 4 wheel vehicle.
That said, I would still like to hear from someone who has some first hand knowledge of the courses available.
