Definiton:
“Sly as a fox" has been a traditional saying for hundreds of years. It means that someone is particularly crafty or tricky. If you're as sly as a fox, you are experienced and cunning and can usually get whatever you want, sometimes by underhanded means.
You are looking for a bison tube placed on Mt. Washington. Across the street is how I came up with the name of the cache. Enjoy!!
Make sure you take in the beautiful views while your're up here.
Happy Hunting!!
