Not ‘dating’ or living in S.F., I can’t attest to the quality of these, but I’ve known Jason since high school and I’d vouch for anything he threw at the wall.

For getting your inner-child geek on, I highly recommend the Exploratorium in S.F., Lawrence Hall of Science in Berkeley, and the Tech Museum in San Jose.

Short hike suggestions, for until your crash hangover goes away: Long Ridge (from skyline out to the rocky viewpoint is about a half mile); Summit Rock (0.4 mile walk; on the Valley side of Skyline, a bit south of Hwy 9 … see http://radio.weblogs.com/0100945/2003/01/21.html#a399 for some photos); El Corte de Madera OSP, near where Hwy 84 crosses skyline, has a cool sandstone (”Tafoni”) lump about a mile from the highway, and there’s the “Methuselah Tree” nearby.

And farther afield (driving-wise), Point Lobos near Carmel is breathtaking (do a google image search); and the walking is not extreme: http://santalucia.sierraclub.org/images/ptlobomp.gif

A dry winter week is a good time to visit Henry Coe park, or the Pinnacles, or Mount Diablo.

Coincidentally I was nosing around XoxoOutliner earlier. Didn’t find what I was after, but didn’t look for long - is there a more recent version browser-only anywhere? (Or…any chance of describing the server interface in words of one syllable that aren’t prefixed “$”).
