This is the BEST time of year to be in San Diego... we were there this weekend (for a funeral unfortunately), but it was just gorgeous. 66 degrees in the evening - we were freezing down there (used to 100+ degrees @ home).
If you're checking in here Sharpie and you're down there for a couple of days - it's worth it to take a day trip out to Julian, California in east county... it's apple picking season and they have the BEST homemade apple pies, ciders and honey out there that you'll ever taste. We're heading back down next weekend with the kids!
Hope you have a great trip - and happy planning! We're already looking forward to Cybernet!!!
