This is one of those caches that seems really hard at first, but once you've seen one, you know. BYOP! There's no need to dismantle anything or break things! Approach from the park side not the fairgrounds.
If you want to listen to a classic while you look for the cache, here's one for ya: https://www.youtube.com/watch?v=uc6f_2nPSX8
It won't really help you find the cache, strictly for entertainment 
Domo arigato for looking for my cache - I hope you enjoy it!
