MountainMacs: Well time to put this one to bed, not only is the road closed but the cache is indeed MIA!
Many thanks to IRLPGUY, #1 FIREFIGTER and LIMOS for their efforts to find it. This was definitely one of my favorite caches and while I am sorry to see it gone I am pleased to see it has been copied in several locations (most likely thanks to an honorable mention on one of the ICENRYE videos last year!)
While I do have an idea for a similar cache that is even cooler than this one (it will also need a key!), I probably won't get around to doing it. So if you think you might be interested drop me a line and I will tell you what it is!
Hope you all enjoyed this one, and thanks for all the great comments and emails.
If you have found your way here because you have just found a key.... sorry... please just discard the key to get it out of circulation, without the original lock they are of little value!
