I think it's safe to say we have all went on at least 1 road trip in our lives.The key to any good road trip?Go with friends you can tolerate for a period of time. Nothing makes a trip more enjoyable then having good friends who share the same interest. Also try and get some video of anything that happens on the trip,Never know when there will be some moments that will never be duplicated.
Some day the back story of that video will come out(Hopefully when I'm dead and gone LOL)
Another key is to have a record of your trip,Sometimes the easiest way is to document your stops

And finally,It's always good to have a recap of the days events
