Good luck everyone! I hope this puzzle takes a long time. Hahahaha. Will add hints every so often. Update [7/22/2020] The city has redone the park, and the cache disappeared along with the bushes! Thankfully, a cacher replaced it for me! Thank you! Anyways, you are now looking for a 35mm Film Canister.
