24 hours

I've driven this trip a gazillion times since I was a kid up the mountains, down through the foothills to the foggy city.  This time I was given a time frame.  I would leave all by myself, get to San Francisco, pick up Amelia and grandma from the airport, spend the night, wake up extremely early and get back home within 24 hours so that Jonathan could make a work commitment. 

We made it home tired but happy.
