Was lucky enough to do Sonoma and Napa with my family back when I was 21. Didn't really like wine much back then and like it less now but getting buzzed several days in a row with my brothers and dad was pretty awesome. It was made more awesome that my brother is friend's with the son of the guy who owns Michel-Schlumberger in Healdsburg so we got a private tour and all the wine we wanted. Went to a bunch of places in Sonoma and Napa, the only other names I remember are Coppola and Williams Selyem. Calistoga is a really cool town and Sausalito and Tiburon are really nice.
