Well it's been over 35 years since I went to Cali for anything other than training and man has it changed. True I was doing the touristy stuff with the family, but man was it expensive.
A few things were interesting/strange, I only saw 6 Porsches in a week and 3 were Cayenne's where was everyone

Nobody anywhere took a debit card unless it was a Visa or Mastercard one; it's like carry around a WAD of cash or use Visa, kind of strange compared to everywhere else...
Traffic was BRUTAL, it took us 2 hours to go 37 miles!, no one used their signal lights not even the cops (ok, maybe 1% of people did), and doing 70 Mph 1/2 a car length DOES lead to rear-enders (saw 3)
Talking to a cabby, I was surprised that being all Eco-friendly CA does not mandate that transport vehicles (cabs, vans, buses, etc) have to be low emissions? He was saying most (cabs) are just gas and his was propane, but I did see a natural gas pump (I think that's what it was). And there was a LOT of transport vehicles
It was nice to see the parks had a lot of healthy choices, we ate right everywhere and I was glad to see we could get good healthy food for the kids too. (there were a LOT of over weight kids from everywhere at the parks)
All in all a lot of fun, no quakes, friendly folks and good food (loved Joe's crab shack), but hardly any exotics in sight, maybe have to go to malibu next year
