It was spontaneous and amazing!
We thought it was going to be a horrible tourist trap, but it only resulted in a moderate tourist trap, because we paid the admission, loved it, and bought t-shirts! hahahaha
First, we were wondering why the dumb entrance was built on a dumb hill that we had to climb for no reason, and then we realize that the "dumb hill" was the lifted edge of the crater.
But honestly (and this could be the synthetic happiness talking), it was amazing and I'm so glad I got to see something so incredible! It was a HUMUNGOUS crater. We thought it was going to be cheapy, with a little dome around some dirt and somebody saying that a meteor fell on that spot at one time, but HOLY CANOLI this crater was friggin CRATER-IFIC.
It blew my mind.
