Livermore to Fresno is closer to 2.5 hours.
5S to Los Banos, cut across 152 to 99.
I live in Walnut Creek, and it takes me 3 hours. Livermore is about 30 minutes in that direction. Not bad.
Looks like lots of folks helping out here. Right on.
Unless you happen to go at commute hour to get out of the bay area...
