If any of you have seen this movie you know what I am talking about. Me and a couple friends would like to do this same thing. Visit states and film wildlife or other things. We would like to sleep in the car or van. Also we want to like not know where we are going next. Which will make it really fun. Though I know some of you are professionals at road trips so I was wondering. What things should I plan,take, precautions. Things like this so please tell me all the info you have to make my experience better.
