Durango Doug took myself and Lisa to a mine he saw from the house driveway. Spontaneous decision at dusk to check it out. Climbing in and out below the gate was a challenge. Worth the effort, though.
Checking out inside the mine, Doug leads me deeper into the unknown. The rocks on the ground are from the mine roof breaking apart over time.
You can see how far back we went inside. Lisa stayed at the gate and probably thought we were crazy. However, she did check it out once we didn't die from a cave-in.
