I'll put it on my calender for October!
However, I don't think track days are any kind of answer for the carnage that occurs on mountain roads. It's all about riding within your limits. And riding up to Palomar is particularly tricky because of the steep switch-backs combined with straights long-enough to get way over your head in the approaching corner.
The skills part that sends riders off the road is still about riding within your limits. The real carnage is caused by trying to pass when you don't really know if the road is clear up ahead. I've seen a lot of dumb maneuvers over the last 30 years at Mt. Palomar, the Ortega highway, up to the Rock Store, the Sierras and Marin County. The problems are passing when the road is not clear and riding over your limits. Then, of course, there's just bad luck.
A useful track day would include having volunteer car drivers drive around the track in the opposite direction on the other side of the track.
