Mystery Tour 2013

Mystery Tour 2013 was a 4-day road trip led by Alex Hirsch and the Gravity Falls crew to find the weirdest tourist traps in Oregon and Northern California.

Hirsch and company left behind several drawings of Bill Cipher in various spots, such as telephone poles and trash cans, and released photos of them over twitter for fans to find. The fans who took a picture of themselves in the same spots received Mystery Prizes.

As of April 10, 2013 Pyramids 3, 6, 7, & 9 still haven't been found. They are located somewhere along the road on the left.

Among the places visited include the House of Mystery at the Orgeon Vortex, a Masonic Temple, Trees of Mystery's Paul Bunyan statue which is located along Route 101, the World Famous Grandfather Tree, and One Log House.
