Ha, one day... in my year-old pamphlet, there are 56 wineries listed, from Half Moon Bay all the way down to Watsonville. One a weekend would take over a year. During a SCMWA Passport (http://scmwa.com/passport/) weekend, Kim and i, together with dr_strych9 and Gina, visited 4 wineries, and that's a good, safe upper limit.
