I live in Colorado Springs and havent seen that in any near by mountains but I would like to know where that is cuz the mountains in the background look like fun riding.
The reason I asked is that I did a search for the mine and it came up as being potentially under "leaf-licker lock-down" with full support of the fed's.....
Anyway, cool looking old machine and the surrounding area looks like it would be fun on a sled!
