I would drive out there at least one time during your normal commute hours and get an actual time. 60 miles in less than an hour in CA seems unlikely. If you are doing this, there has to be others with the same idea on the road, creating traffic.
Assuming 5 days a week, 4 weeks a month, 48 week year, that is going to put nearly 29,000 miles a year on your vehicle. Make no mistake, that is a large expense. Gas, maintenance, wear and tear, it all adds up. Is there any chance to car pool with someone?
I had a 27 mile (one way commute) that took about 45 minutes (30 minutes freeway time) in So Cal for a couple of years. I moved about a year ago and now its about 7 miles & 15 minutes. There is no way I am going back to a commute longer than 30 minutes. The time on the road that is completely wasted. By moving a got an extra hour everyday to do other things.
My prediction, you will convince yourself it isn't so bad and go ahead and do it. Then after 12 or 18 months, you will wonder what you were thinking and absolutely hate it.
That being said, I do wish you luck in your new job. It is nice to see, in this economy, someone get a good opportunity.
