Foamhenge (near Natural Bridge), a giant foam Stonehenge replica, is a quirky photo op. Just south of Lexington, the Blue Ridge Parkway starts—if you have extra time, drive a segment for breathtaking mountain views.

Fatigue management: Avoid caffeine after 4 PM to maintain late-day rest. Use apps like iExit to find clean restrooms and gas stations. Consider splitting the drive with a stop in Harrisonburg, which has affordable motels and a vibrant downtown with craft breweries (e.g., Three Notch'd).

As you leave Princeton, the flat coastal plain gradually gives way to the rolling hills of central New Jersey.
