This is a very easy challenge that anyone can qualify for, it just takes a little research and planning! To qualify you must is to find a cache on its "birthday," or the date it was published (sorry FTFs don't count for this challenge- you must find it after it has been published at least one whole year). For instance, if you found Team Conway's JEEPSTAFF cache (one I HIGHLY recommend) on its publish date of December 13 then you would qualify!
Once you qualify simply find the final hide by looking at the additional waypoint. The final location is visible to all!
Finally, here is a Project GC checker for those who want to see if they already qualify.
