A week from now, along with two friends, I will be heading out on a road trip from Florida (Satellite Beach, along the I-95 corridor) to California (Vallejo, off I-80 in the Bay Area). I've come across a couple of options for our routing and was wondering if anyone had advice. The southern route would mostly be I-10 to I-5, the intermediate route would be a combination of interstates and state roads that the online AAA TripTik spat out (I forget the exact route, but it goes through Amarillo), and the northern route would take us up through GA, TN, etc. and use I-70/I-80 which would go through MO, NE, CO, etc. to CA.
I'm personally favoring the northern route because it passes by more major cities and goes through the Rockies, etc. while I imagine the southern route would contain a whole lot of desert and flat stretches through TX/NM/AZ. (We would likely take the southern route on our way back in August to vary things up. I don't like the intermediate route at all. Too many road changes.)
Any pros and cons to either route or alternatives? We can't afford to take smaller back routes because we basically have slightly under a week to get there. Thanks in advance for any help!
