Thanks for the shout out, @LSLGuy, but although I taught High Performance Drivers Ed for almost a decade, that was all at tracks on the East Coast, where I lived. I drove a few events in rented cars at two tracks just north of L.A., but never got to Laguna Seca. Not having a chance to drive there is undoubtedly my greatest regret in my HPDE career. It’s an absolutely legendary track.
I did the Skip Barber three-day school at the Mid-Ohio Sports Car Course (another great track) in the summer of 2001, and it was definitely one of the highlights of my driving career. So I’m insanely jealous of @Robot_Arm. You will have a great time!
Others have provided plenty of info about things to do off the track in the area. And with only a few days to go, there’s not much I can tell you that would help you prepare for the school, other than to say, have someone take pictures of you in your car out on the track, and come back and tell us all about it afterward.
