THE CACHE IS AT THE LISTED COORDS.
The objective of this challenge is to have found 400 caches that were HIDDEN/PLACED during the years 2004 and 2005. All cache types qualify including Event type caches as long as there were HIDDEN/PLACED sometime in 2004 or 2005. As an example if you found 175 caches that were placed in 2004 and 225 caches that were placed in 2005, then you qualify. Demonstrate you qualify by either using the Challenge Checker on Project-GC (click on link below), creating a Bookmark List, listing the 400 caches in your log or providing a screen shot of the "Finds by Placed Month" chart that can be produced using a GSAK macro (example: HTML_PlacedDateMonth). I have included a screen shot of my "Finds by Placed Month" chart. Mac users can easily see their totals by year by going to MyGeocachingProfile.com
You may find this cache prior to qualifying. Just sign the log and write a note on the cache page indicating your progress on completing this Challenge. Then when you qualify you may claim the find on the cache.
