Also, the hint is now useless but I don't want to change his original description:
You are looking for an Ammo Box. This is one of those little visited or known County Roadside parks. It has a short walking trail, Picnic Table and I believe Restrooms...the cache is just in the remote area of the park, where some of the county keeps stuff. Take the kids, a picnic lunch and enjoy the day.
