Here and there turned out to be Bartlesville (OK), which is only about 50 miles north of Tulsa, in the Osage Hills. It's very pretty country. Bartlesville grew up around the oil industry, and as the home of Frank Phillips, founder of Phillips Petroleum. There is also a strong Native American influence in Bartlesville. During the oil boom early in the 20th Century, B'ville saw growth and great wealth.
Frank Lloyd Wright's only skyscraper is in Bartlesville -- the Price Tower. There's an art gallery inside, a cocktail lounge on top, a hotel, and tours.
Frank Phillips' home is now a museum and also has tours.
The train station is very nicely restored.
Bartlesville is apparently having one of those community art projects, the likes of which my mascot Tripper the Penguin was born in Tulsa. In the case of Bartlesville though, the giant artfully-painted creatures are bison! I managed to snap a photo of this guy from the rear -- a tribute to the work of the artist Mondrian.
