^ hey that's great!
It's real fun when you get point-by's from some hot cars. I've got a handful of videos on youtube doing lots of that since you get a mix of drivers with different skills and/or the will to "push it" at an HPDE.
(I saw one guy total a C5 vette on his first HPDE with the instructor in the car, sometimes bad things happen.
Anyway, glad you had fun.
Now I dare you not to start thinking about going racing.......
These links will tell you how to get a license in SCCA or NASA.
