An RV would be cool, you can drive someplace, park, have all your food there, and a place to sleep, and all your toys. Roads are kind of crowded though, and your dealing with a lot of people around and such. A boat is kind of similar, it can hold all your stuff, but you do have to launch it. The nice thing is that its not nearly so crowded, there are no lines to follow (roads), and it is completely different than land based activities. Get a sailboat, its the most expensive way of traveling for free.
