Soaring around Bay Area early Feb

Hi all,

I am German glider pilot and will be working in the Bay Area early Feb
of 2009. As I will have one free weekend (most likely the weekend of the
7th) I thought I'll check out soaring possibilities.

Now it's highly unlikely that I will have my German license transferred
to a US license (lack of time and lack of instructors this side of the
Atlantic ocean). I would need a school/professional gliding operation or
a club willing to let me fly with an instructor. Does anyone have any
recommendations for me? What's the wave situation like that time of the
year? Thermal, I suppose, I can forget about, right?

any pointer, tips and recommendations warmly appreciated

cheers

Torsten
