Find four other caches : GC1EJBH, GC1EJBV, GC7W918, GC1ENHW and GC1ENJ5. Use the information provided on each their logs, below the cache name but before the first-to-find log. Three of them contain digits that you will need, and the fourth will tell you the order of these digits.
When approaching, you'll think that the difficulty should be higher, but, to a geocacher, the location should look like something is being hidden.
If you take a trackable, at least leave something that will fit in the geocache, preferably another trackable.
In case you got to the puzzles early, you will need to swap "E" and "F" in the final coordinates. If you got there later, use them as-is.
23 March 2011: I recently replaced the Post and Roadside caches. I think I got the hints correct, but I may have swapped the hints in these two.
11 December 2020: From the coordinates that you get from the other caches, add N 0.008 and subtract W 0.027. This is where you'll find the cache.
2022 June 2: I recently completed a maintenance run on all of them. If you have these values there is no need for an offset. If you got them from before this date then you will need the offset. If you have some before and some after then send me the values you got and I'll send you the latest values.
