I wanted to add a challenge in this series that had a nice round number to it, which makes it a bit more appealing to those of us who can't count much past ten without taking off our shoes.
For this challenge, you must have found at least ten caches, ten days in a row, over ten consecutive months, so that your calendar stats page reflects a 10 x 10 block with 10 or more days in each square. For each month, it must be the same ten days in a row. It doesn't have to be the first ten days, it just has to be the same set of ten days for each month.
In this example, you can see I don't qualify for this challenge, yet, but this was the best "block" I could make:
However, in this example, you can see that this cacher qualifies for this challenge:
Cache is a camo'd pill bottle. If you wish, you may post a photo of your calendar stats showing your "block," or a link to your statistics page with your log.
