We had originally planned to spend Saturday doing "touristy" things in San Francisco - Ghirardelli Square, walking along the Embarcadero, and the Ferry Building.  But after waking up at 6:00am (we are naturally early risers and even more so now that Alex works on East Coast time), we decided to head out to Muir Woods and do a nice, long hike.  We both have been missing traveling and thought a beautiful hike through the woods would do us well.
