Medium sized Lock & Lock container, on the Blue trail. From Parking, take the Yellow trail, left onto the Blue trail, then left again onto the Blue/White trail. The Oswegatchie Hills Nature Preserve trail guide shows the Blue/White trail terminating at Chapman Woods Road.
This cache will bring you on a nice hike to a nice spot. I placed it at a significant milestone in my life. Its filled with items with "positive" messages, and a small prize for FTF.
