In the central OK city of Arcadia, you’ll cross several miles of farmland before happening upon an interesting place on the north side of the road. Not marked with anything in particular, it nevertheless stands out because it's a house, garage, and sprawling piece of property loaded with Route 66-type memorabilia. Turns out it's called the Oklahoma County 66 Auto Trim & Mini-Museum, although it's very informal.

You know, you're used to older buildings and artifacts throughout the Oklahoma countryside, and suddenly, there's Pop's, a futuristic beacon rising from the grassland, fronted by a 66-foot high sculpture with a Coke bottle shape that lights up with crazy colors at night. How does one describe Pop's? It's an ultramodern gas station and diner, with a 100-foot sweeping canopy outside to cover gas-pumping patrons and glass walls adorned with thousands of soda bottles – all real and filled – on the inside. Over 500 varieties of sodas are available at a given moment. It's kind of like a post-modern take on the traditional American diner and gas station, and definitely worth checking out.
From Arcadia, Route 66 makes a beeline west and crosses Interstate 35, the north-south backbone of Oklahoma. At this point, you're firmly in the Oklahoma City suburbs, and the first town is a big one.
