Exactly the point I was going to bring up...
Breckenridge exists within the White River National Forest. From what I could find and understand the construction of a permanent structure is illegal within the National Forest and I will assume no permit was given for it... Therefore this was an illegal structure that they have every right to demolish, along with rest of them. Nothing left to argue.
Was it something that they jerry-rigged? It almost looks like a historic structure.
