Clive,
Welcome to the site.
I actually live in the South Bay, but often ride up to the Rock Store or up Angeles Crest to Newcomes for a Sunday scoot. Been a while since I've ridden Ortega Hwy, but if you'd like to get together soon for a ride, send me a private message here one day, and I'll see what we can cook up.
Cheers,
Dwight
(it seems with all the new SoCal people arriving everyday, I think it just may be a good idea for me to set up some kind of gathering and ride around here pretty soon)
