What letter comes after J? 20K of course! Traditional Cache

This cache is in honor of Mr. and Mrs. J.  I was trying to place this cache before the jazzmasters duo hit their 20K mark but they had to go on a power trail and hit 20K way before I was even ready!  So here's the cache that I'm hoping to place before they at least hit 20.5K.

Congrats Fred and Linda, it's always a pleasure caching with ya'll!
