Take a wander over to Midnight Creek and find a cache! You can technically drive to it on a 4 wheeler or dirt bike, but that's lame. Instead, take one of the many routes around the area and make it a nice hike.
If you attempt to find it after doing Rock Knoll, know the ridge is pretty steep and there is bushwack in spots.
Cache itself is a green bottle hanging on the branch of a double spruce. Use spoiler pic if you need.
