Any advice, tips, or hacks is greatly appreciated. How to plan it out and how to cheaply get from place to place. Basically anything you can tell me about going on a solo roadtrip would be great.
Thousands of youngsters do exactly what you suggest every spring, and they don't know any more than you when they set out. Head for a warm climate.
