We met up with Aunt Annie & Matthew this past Sunday for a quick trip to Flagstaff. We took a little adventure to a lava tube, just outside of town. It is basically a cave made in the ground some hundreds of millions of years ago by flowing lava. We didn't hike very far into the cave, but enough to get the feel of the cold, damp space. The kids weren't scared at all, and Jacob even wanted to lead the way. At one point, past the light of the entrance, we all turned off the flashlights to see how dark it was. Pretty cool. We spent the rest of the day perusing the shops of Flagstaff and having lunch at an outside restaurant patio.
