Cozy Dog Drive In

A UNESCO World Heritage Site at 30 Ramey St, Collinsville, IL 62234, eight miles east of downtown St. Louis off I-55/70 and I-255. The pre-Columbian city of Cahokia reached a population of nearly 20,000 around 1100 AD and covered 4,000 acres with roughly 120 earthen mounds. The 100-foot Monks Mound is the largest pre-Columbian earthwork north of Mexico. Grounds are free and open dawn to dusk daily. The Interpretive Center lobby (restrooms, gift shop, site model) is open Wednesday–Sunday, 9 am–3 pm.

Founded in 1928 by J.P. Walters and John Geske as a sandwich stand in a truck mechanic's garage on US Route 66, the Dixie Trucker's Home in McLean is one of the longest-operating truck stops in America. Located at 260 Dixie Rd (Route 136), McLean, IL 61754, off I-55 exit 145, it sits roughly halfway between Chicago and St. Louis. The Geske family ran it from 1928 to 2003; it survived a fire in 1965 and closed for only one day. Now operating as a full travel plaza, it remains a documented Route 66 landmark.

Galena's Main Street curves through a remarkably preserved 19th-century downtown where over 85% of the city's buildings are on the National Register of Historic Places, including the Ulysses S. Grant Home at 511 Bouthillier St (coordinates 42.4112°N 90.4246°W). Named 'Best Main Street in the Midwest' by Midwest Living, the strip hosts galleries, antique shops, restaurants, and outfitters. Galena draws over 1.5 million visitors annually and sits at the gateway to the Driftless Area — the region's best riding terrain, including Blackjack Road, a 15-mile rural road that twists north toward Savanna with Mississippi River views.
