The ghost town of Amboy was once a major stop along Route 66 until Interstate 40 was opened. The city only has 10 remaining buildings, Roy's gas station and motel cafe being the biggest landmark. You can stop in for a Root Beer and wander through some of the abandoned hotel rooms with art installations.
In 1959 the towering retro neon boomerang sign was erected, and is the most charming feature of this stop. A few rooms from the hotel have been left as museum pieces, with furniture and objects from a past time. You can only view these rooms from outside the glass walls. Also, the old motel is mostly gated off, with some vintage cars on the interior. I'd pay a pretty penny to get past those gates to shoot some photography.

Just a few miles down the road from Roy's is Amboy Crater, a 6,000-year-old cinder cone volcano that rises above a lava field. This cinder cone is estimated to be 79,000 years old. You can hike to the rim using the western cone trail. There is a parking lot you can turn into with viewing deck. I loved seeing all the plants spring up from the black lava forms. New life sprouted from the darkness.
