Pre-ceremony picture locations in Sonoma?

Hi there! Does anybody know of a good place to take pre-ceremony pictures in Sonoma, California? Preferably in Sonoma proper or Glen Ellen, but we just need a spot to do portraits before the ceremony begins in downtown Sonoma. We'd love vineyards in the background but haven't had luck finding a winery that will allow it if we aren't actually getting married there. Thank you in advance for your help!
