U.S. Counties Triplet Challenge Mystery Cache

This is a challenge cache. The cache is at the posted coordinates. 

The rules here are simple. You must have found a cache in 333 United States counties.    

Any cache type counts.

The final is a typical gravel road hide D1.5/T2

I prefer that the log not be pre-signed, but if you do, please claim the find on the day you qualify. 

You can count this cache as your final required cache. It is in Story County

The M4ISU kids are triplets, so the number 3 is special to us. I have always enjoyed watching the maps fill with counties and states during our cache trips. I have had the goal of 333 for some time, just recently knowing that when we got there that I would create a challenge.

Please do not fill your log with a list;  use bookmarking, GSAK or any other summary tool screenshot that you chose to display your finds. Our example is attached below, just above the logs section. I use MyGeocachingProfile.com
