Pre-purchase all the snacks and drinks for your green road trip. Not only will this save you lots of money, you will be able to choose healthy organic snacks in eco-friendly packaging. Choose water and other beverages in recyclable bottles to last the duration of the trip. Purchase the items from your local natural food store, they may even have some ideas for great road trip snacks you had not thought of. Just make sure to not go overboard, you still need room for your luggage!
