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.
IN ORDER TO LOG THIS CACHE AS A FIND, YOU MUST COMPLETE YOUR JASMER GRID. The Jasmer grid will be filled when you have found at least one geocache published in every month since geocaching began. You will need to post a picture of your grid (see example above) or a list of each cache (or bookmark of the caches) you found to qualify for this challenge. 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.
