There are plenty of playgrounds for children...why not have something for adults? Kasson seemed to be lacking higher-terrain-rated caches, so this cache was born. It shouldn't bee too scary, it just requires a little arm strength.
You should be able to spot this one if you wander around Ground Zero and keep your keen eyes open wide. Once you spot it, the fun begins! 
...get some exercise and see if you can entertain the onlookers.
NOTE: This is a high-muggle area, so be sure to bring some distractions...you'll be in a park near a playground! You can "challenge your kids to a competition" to create a suitable diversion, hiding your real mission.
GOOD LUCK ...and HAVE FUN!
