Hi, I'm moving my girlfriend out here to California (Orange County) from Minnesota (Minneapolis) in July. We'll be driving a big 2-3bedroom-sized u-haul. I'd like to avoid mountain driving if I can. I'm assuming that parts of the 70 and 15 have some mountain roads so is there another route anyone can suggest? Maybe taking the 40? There really are no time issues so going out of our way a bit isn't going to hurt. Any help advice would be greatly appreciated. Thank you very much.
