The cache is 50 cal. ammo box, located along the Montour Trail. It is just about midpoint between the Hendersonville 2 access and the Valley Brook Rd./Route 19 access.
There is trail parking available if you take Buckeye St. (a little dirt road) off of Valley Brook Road. This will start you very close to the cache. For a better hike, park at the Hendersonville access. You will have a flat walk of just over a mile. You'll cross a big bridge, go through a tunnel, and cross another big bridge. After the second bridge, you can start considering a bushwack to the cache. You'll need to go about 200 feet uphill.
Remember to Trade Fair or Trade Up, and hide the cache well when you are done. Consider leaving some Little Plastic Building Bricks for your swag, to keep with the theme.
A safety note: There are no steep cliffs right around the cache, but there are some not far away. Don't let your small children wander too far.
Be safe, have fun, and above all: LEt's GO geocaching!
