We visited the US Botanic Garden’s annual “Season’s Greenings” display titled “Roadside Attractions” featuring plant-based recreations of iconic sights from across the United States, with G gauge model trains chugging around, below, through and above the displays.

A classic example of roadside architecture, this diner is shaped like a giant hot dog complete with toppings. The hot dog is 42 feet long, and the building weighs 18 tons. The original owner envisioned a chain of hot-dog-shaped diners across the state, but his business closed and he sold the building. Successive owners have relocated the diner from Denver, to Aspen Park, to its current location in Bailey, Colorado. The diner underwent renovations and reopened for business in 2016. It serves a variety of local fare and, of course, coney-style hot dogs.
