Just a quick tip for anyone else who may be planning their own crazy, stupid fast road trips.
Here are some free apps that made my journey much more manageable:
Instagram: One app lets you take a picture, add some cool filters, then post it simultaneously to Twitter, Facebook, and Tumblr.
MapQuest: Nearly a free GPS. Its only limitations are signal range and strength. But anytime I got lost I could push a button and it would walk me through the directions to my next location.
Tumblr: Works just like Tumblr, but, by using the record-audio feature, it can basically turn your iPhone into a portable voice recorder for interviews on the fly.
