I can recommend Attitude Aviation at Livermore. They have all the normal stuff, then everything from a Citabria to a L-39! I had a go in an Extra 200 2 weeks ago, with a fantastic instructor called Luca. A few strands of spaghetti short of a full dinner, but huge fun. Nice location too.. .. .A PPruner called BayAreaLondoner will also have some strong views - he flies from San Carlos or Hayward?? I believe.. .. .Good luck
