Early commute

I went to Oakland airport in early morning, staring at 4 a.m. and back by 5:45 a.m. When I was going back, the 580 freeway was a sea of lights all the way through Livermore and across the Altamont. The merge area with I-5 was moving slowly, though not stopped completely. Lots and lots of trucks, too.

I keep wondering, who are these people who come to work at 7 a.m. Must be retail employees of some sort. When I commuted, I do not remember getting to work before 10.
