Capturing the road trip memories is part of the fun! I use a GoPro because it's specifically made for adventure!
Don't forget the tunes! Jam out to your favorite music, or make a list of the podcast episode's you've been wanting to listen to.
Get the paper map. When you're on a deserted highway with no cellular service and no access to Google Maps, you'll thank me.
Stop and grab a bag of ice, and fill your cooler with your favorite drinks and chilled snacks. I threw a pack of bologna in my road trip cooler and didn't have to stop for fast food at all.
