There are road trips, and then there are legends. This summer, the storied stretch of Route 66 unfurling across southwest Illinois invites discerning travelers to indulge in a journey that is as nostalgic as it is unexpectedly refined. Along the “Last 100 Miles,” a ribbon of Americana comes alive with centennial celebrations, artisanal flavors, and curated experiences that elevate the classic road trip into something altogether more sophisticated.
