Discovered this park by accident one night while driving through. Not sure what the actual name of this park is but there is a stone marker under the tree in the park dedicated to Michael Wagenbach so Wagenbach Park sounded like a good fit. There is also an inscription on one of the painted rocks in the middle of the park that was interesting to read. If you have any more information as to what the name is please specify in your log.
As mentioned before you're looking for a nano cache. Unfortunately a nano really was the only logical choice of container for this spot due to potential muggle traffic and lack of hiding spots for something bigger. The hint is hopefully generous, so use it if you want a quick find and BYOP as mentioned before.
