I've driven through AZ several times but never went that way. Driving down 17 from I-40 towards Phoenix at night was actually pretty dope. I swear that's the longest downhill drive I've ever been on.
I drove from Connecticut to Geneva NY and back in September which was sick. It looked like a picture straight off a calendar or something with the fall leaves, mountains, and there a couple small waterfalls.
I don't know if that tops the drive down the PCH on a clear day tho.
