I use to live in so cal-the inland empire. Depending where you're going & what time makes all the difference. Going east to the desert wasn't bad at all, even when you're driving 70 miles/hr and people are zipping past you..I remember working in Malibu, and we left early because it was the start of a long weekend. My 90 mile trip took 5 hours!! The 91 has always been terrible..15 can be nasty on a Friday..
