There are plenty of destinations to keep you busy this summer, and throughout the year -- especially if you're a fan of the unusual.
We've been on a hunt for lesser-known gems in our Hidden Valley series. Today, from abandoned dog tracks to castles, we bring you a few of our favorite oddball spots.
10. Black Canyon City Dog Track
The Black Canyon City Dog Track, about 40 miles north of Phoenix, is both a mecca for squatters and urban explorers and a fascinating study in decay. This massive property has been falling into rapid disrepair since the late 1980s, and remains one of the most accessible abandoned sites in the Valley.
