There is now a trail leading right to it. Here is a trail junction to get you pointed in the right direction.
There are several loops of unmarked and unmapped mountain bike and hiking trails over here near the real Hogback Mountain. From the large parking area/trail head on Route 9, follow the White's Loop trail to an unmarked trail junction. Stay on the trails to get to the cache -- it's much easier than bushwhacking through these woods.
You will be looking for a camouflaged matchstick container stuck in a place not far from a trail intersection.
You could go either way from here to get to the summit of the real Hogback Mountain. Taking the trail that goes northeast is more direct (that's the right turn, if you're on your way in).
This cache was placed to mark the route to Bren1467's 1,467th Cache!
