Matt, my son, and I put a little work into making this cache so it would be a fun one to find. No micros stuck on a PUB here. At Ground Zero, there are several good hiding places so your 'geosenses' will come in very handy. Also, you will need a TOTT or two, this is not an easy grab even after you find the cache. So since there is a little difficulty in qualifying and retrieving this cache, there is an Abraham Lincoln to greet and go home with the First to Find and retrieve.
Your cache log must state a GC number and the country it is in (no need to put the cache name unless you want to). You do not need to qualify for this AFTER the publish date of this cache, if you have two countries under you belt, you already qualify so come and find it. But you only need to list two different countries. There will be more "Country Challenges" in the future.
Please put the cache back the same way you found it. Do not make it harder or easier for the next finder. This will make sense once you find the cache.
While it is not necessary to log the cache, please feel free to give a little story about your other country caches. For instance, my second country find was in Canada. Eva and I took an Alaskan Cruise that started in Vancouver, Canada. So we flew to Vancouver and found a cache there before our cruise. This got me hooked on finding caches in other countries! I would love to hear your stories!
