A drawback to being popular and having many friends is everyone traveling with you has luggage to pack. How will you fit it ALL in your car comfortably? Urgh..
If you have at least four friends driving together on a road trip, you need to devise a voting strategy on the music selection. . . "taste" in music gets intensely political AND personal.
What friends enjoy together most is satisfying "the munchies", and while on the road with a schmorgesborg of junk food galore. . . BE SURE to bring Pepto Bismol tablets!
If you've ALL made it to your holiday spot without killing yourselves and STILL remain friends. . . You've passed the Best Friend Forever test. Congratulations!
