Come take a nice walk on the Countryside Conservancy's Messimer Preserve! Park at the same coordinates used for "Must Love Big Dogs" or drive down the road a little farther to the small area at the trailhead. This is helpful especially if you need to avoid the dog; however, I do not recommend the road for all vehicles. Having some clearance does help, and there can be mud. Use your own discretion. There is a Countryside Conservancy sign at this area too.
This place is beautiful! Cache is an ammo can.
Hunting is allowed by permission in this area. We saw an old tree stand that was falling apart. I'd wear orange during hunting season just in case.
