I'm riding as a passenger on the first road trip I'll be taking with my girlfriend and her parents. It's roughly an 18 hour drive and I'm unable to participate in a driver rotation, so I'm looking for snacks and other support I can provide to be just as valuable as a passenger. What are some of your favorite road trip snacks? I plan to make some chocolate covered pretzels and bring some assorted snack mixes from Farm & Fleet.
