I really love Challenge Caches. I qualified for and logged quite a few this past year and now I am adding one for you to attempt. This one is not very easy to qualify for. The difficulty and terrain are reflective of the effort it will take to qualify for this cache. The actual hide is a 1.5/1.5.
IN ORDER TO LOG THIS CACHE AS A FIND, YOU MUST FIND A GEOCACHE IN ALL 48 OF THE CONTIGUOUS UNITED STATES PLUS WASHINGTON DC. In other words, the entire USA minus Alaska and Hawaii (although if you have those too you still qualify and I am jealous!) I can verify your qualifications in your public profile. Once you have met the requirements, go find it and sign the log. The Difficulty and Terrain for this cache are a factor of the effort you will have to put into qualifying for the cache.
