I hadn't heard of the Meteor Crater in Arizona until we had hit the road on Route 66. But that's the beauty of the Mother Road, there are so many friendly faces and fellow explorers, that sometimes you learn about things as you go. The Meteor Crater was one of those, but it is an awesome thing to see, and definitely worthy of being considered a Route 66 Landmark.
As busy, working people, we need to get the most out of our vacations when we have them. We could use a shortage of time as an excuse to not go at all, but that would be a huge mistake. While having more time is always better, not having “enough time” to see a destination in it’s entirety is no reason to avoid the destination all together.
