This is a Challenge Cache and IS located at the posted coordinates. In order to claim a find you must have met the terms of the challenge. You may sign the log at any time and post a note on the cache page. Any "found it" logs that don't qualify will be deleted. There is a challenge checker you can run to see if you qualify.
Is it time for a road trip or are you already on one? I enjoy traveling and grabbing caches everywhere. I have seen and grabbed a challenge for two caches 100 miles apart. This challenge cache will require a little more. To claim this cache, you need to have found two caches 500 miles apart, plus or minus a mile. Best of luck.
Do you qualify? Check here.
Cathy'sClown has used Project-GC to see if they qualified for this challenge and they did. He found GCYFEM (Mall RING Road) on 2013-02-21 and GC9F60 (Oh Brothers, Where Art Thou?) on 2019-04-20, and they are 499.435 miles apart.
