Just outside of cheyenne wyoming on the main interstate there is a point of intrest stop right in the middle of the freeway. It is known as the tree in the rock. This is one of the first trees in this area, and happens to be a stop I make every year as I travel through this way. I love this tree, as it has grown in my lifetime from a small four foot tree to this beauty. It is actually growing inside the rock too. There is more history to this, so if you have time, look it up on the net. It is a pretty neat story.
