I didn't realize, nully, that you were so close to Ghirardelli Square (that's what it's called, correct?)....I've been by there (not inside), last visit to SF, some time ago. (That's not counting my pit stop at the SF airport last Christmas...when I bought Ghirardelli and Sees chocolates.)
I do recall you saying one time that you had POUNDS of chocolate.....but that's likely stale by now, lol. And, this trip to So. Calif. will not likely allow a "stop over" in SF...though that chocolate is to die for.
So.....less than an hour's drive, huh? : )
