As wvcoalcat said, welcome to caching in Wild, Wonderful West Virginia! Although I just found the Middle Mtn cache a couple months ago, I don't remember the exact hide (of all the things I've lost, I miss my mind the most ). I don't remember it being a real tough hide, but these things can be tricky sometimes ... even for a seasoned cacher. As others have mentioned, once you find it, you'll be amazed that you missed it before.
I found the first stage of the Bickle's Knob multi a year ago but couldn't find stage two. Then went back this year and didn't have the stage two coordinates in the GPSr still, so we stopped to look at stage one again and this time couldn't find it! ... Even though I swore that I knew exactly where it was! I was eventually able to find the stage two coordinates that I saved on my laptop and we were able to finish the cache, but I was sure that stage one was gone. Now I see that someone else found it less than a month later. Sometimes caches can simply disappear into thin air, only to reappear when you turn your back.
Being from Elkins originally, I travel back to the area once every month or so. If I can be of any assistance while in town on my next trip, left me know.
Good luck and keep at it!
