Cross-country road trips are as much a summer tradition as barbecues, fireworks, and clambakes. Packing up the car and heading off for adventures unknown makes for some of the fondest travel memories, especially if the trip involves stopping to explore attractions along America's iconic roadways. In honor of the great American road trip, here's a guide to some top cross-country road trip stops along Interstates 10, 40, 70, 80, 90, and 95, as well as the legendary former Route 66, much of which was later replaced by Interstates 40, 44, and 55. Most are cheap or free; the others may be worth a splurge.
