Gas is cheap and the countryside is free – good news for a summer or fall road trip. Unfortunately, lodging is not free, which is why budget road trippers often choose to pitch a tent. Sleeping under the stars in wilderness areas or National Forests also gives you the chance to stretch your legs with a short hike pre- and post-drive, or mellow out with some fishing and a campfire meal. Here are campgrounds that connect the northern route from New York to Oregon. (Prices are for tent sites, and many include access to shower and laundry facilities.)
