Another of my North America series (Challenge caches that I have found around North America)
This one is similar to a cache that I qualified for in IOWA
In order to log this cache, you must have found and logged at least 100 caches in at least 20 different D/T rating categories/grid squares.
Please use

You can sign the log at anytime, just post a note that you did, then log it online when you complete it.
