My main problem is that there is nowhere to fly on the Peninsula or the Santa Clara Valley. I have flown 1/2 A at the Department of Motor Vehicles truck testing parking lot, with complaint about the noise only from an RV squatter who is unlikely to call the police because he has probably been parked there much more than the allowed 72 hours.
The nearest organized site I know of is across the Bay, about an hour's drive when the traffic is light.
