Correct. It's about 380 miles. It's a straight shot, though, so that helps.
This was my U2005 tour, but, in looking at my car after the drive up to and back from San Jose, it's more like the dead bug at 80 mph tour all over my car tour.
Bring the sunscreen, lots of water and some source of shade - you will be in the direct sun until 1PM or so and it is frickin hot here in Phoenix right now
