Wake School in CA ( San Fran / Petaluma ) ?

I will be staying in Petaluma outside San Fran ( Rohnert Park area ) mid September and will have 2-3 days leisure time and would like to get some lessons, do some riding etc. My season winds down around this time of year at home.

Can anyone recommend a good, well equiped school for beginner intermediate riders in this area..I am hoping to find something fairly close to my hotel if possible.

Thanks

Colin
