The cache is at the stated coordinates but in order to log a 'Found it' here you must fulfil the following conditions.
1. Sign the log
2. To have found caches containing at least 40 of the 41 available non attributes . Ie they are not attributes that apply to that cache or they are not allowed at the cache site or on route to that cache. These appear on the cache page as an attribute that has a red border and a red line through it.
You can check if you qualify for this challenge by looking up your profile on the Project Geocaching site, scroll to the bottom of the stats page. I can also look here to see if you qualify. If you choose to hide your stats on Project Geocaching you can either post a screen shot of that part of your page or you could list all the caches that qualify you for this challenge ( please only do this if you hate me).
You may sign the log any time you like and post a note on the cache page, but please don't post a Found It log until you qualify
