This is at least 81 finds and if you’re like us, many more in your journey to complete the grid. There is no state or date requirement. We qualified for this challenge in 2014 and our currently working on our second through fourth loops of the grid.
You can prove your qualification by making your statistics public for quick verification. If you do not want to do this you will need to create a Bookmark with all 81 caches plus this cache. Or you can list all 81 caches in your log. Good luck, travel safely and above all, enjoy the journey.
