Yesterday, we went biking down a 23 mile crater. We took a shuttle to the top of the crater, and then we looked around before biking down the crater. At the beginning, it was very fast. We flew down the road, which evetually turned into a highway. I made a sharp turn and fell downwhile on my way down. We had the option to stop for food, but we didn't. We just went all the way down. There were sometall hills at some parts, but overall, it was fun.
