"Miles and miles of Texas."
How I did it: I packed up my car with everything it would hold, drove from Santa Fe (where I started) to San Diego. Picked up my driving buddy and his backpack, and began to journey back home to Georgia!
We took I-10 from California to San Antonio, trading driving shifts, sleeping, and talking to keep each other awake. From San Antonio we shot North on I-35 to Austin. In Austin we stayed with my friends from college, partied, and slept.
Two days later we drove from Austin to Pensacola, and stayed in a trashy motel there. The next day we set out across the Florida panhandle to Jacksonville. My car was COVERED in those low-flying black lovebugs that have taken over the North Florida swamps.
In Florida we crashed with my cousin in Jacksonville for a couple of days--most of which were spent at Ponte Vedra beach. Then we got in the car one last time and headed North on Georgia backroads towards Athens.
Lessons & tips: Plan your trip around where you know people! Stay for a few days and have them show you around.
Avoid hotels if your on a budget. Sometimes they're a necessity, but they can be so sketchy right off the interstate.
Red Bull is your friend. Even if you hate its carbonated pixie stix flavor, drink it down and you will never tire!
If you're moving, pack the trunk wisely. Nothing loose in there! You may need to get at your spare, after all.
Backroads are so much nicer. Do the research and take them whenever possible. Many have expanded to four lanes, and when you're out in the desert there are so few cars that you can still fly on two lane roads.
Two words: Radar Detector. It will change your world. Just be careful--they're illegal in some states.
Make room for a cooler. Pack yourself some fresh snacks and meals and eat them picnic style at rest stops. Your stomach and your wallet will thank you.
