Butterflies, butterflies … They’re Everywhere! Traditional Cache

Butterflies, butterflies ... they're Everywhere!   Now there's a Cache too!  Easy Park and Grab as you enter the City of Joplin, Mo.  I found a similar Cache in town and decided these Butterflies needed a Cache too!  Tried using a Magnetic Container but no Luck as Sign/Mounts appear to be Aluminum.  We'll see how this works out this time; hopefully it will last for a Few Smileys!
