Good location for flying near San Diego ?

Dear all,

I'm from the Netherlands and will be in San Diego for work for about a
week in March. I might have a spare day or afternoon to spend on some
soaring in the area.

I have flown at Cal. City a long time ago and was impressed (by the
desert, the wave and the metal from Edwards) - but that's too much of
a drive from San Diego. Still, repeating the experience would be
great !

Any recommendations for sites where an 'advanced ride' (I have around
~800 hrs) would be possible, at a reasonable driving distance from San
Diego would be appreciated.

Greetings !
Dirk, The Netherlands.
