There are trailhead coords. The trailhead can be tough to find, so find the James Brown EP Parks sign, and go to the Left/South side of it to find the trail. You may see "No Trespassing" and "No Motor Vehicles" signs, but they are referring to the nearby driveway to the local homes. The trail will stick close to the driveway for maybe 75 yeards before heading down to the river bottoms.
From there, everyone likes an ammo can in the woods.
This EP Park is open from 6 am to 10 pm. This cache follows all EP rules.
