When university students in Halifax want to go sliding, there are 4 places that generally pop to mind: Citadel Hill, The Pit, Gorsebrook Hill, and The Motherhouse.
The Pit is my favourite spot for sliding. It's hard to find a hill this steep that isn't dangerous. :)
The cache is a film canister, so bring your own pen to sign the log (though there is a very small pencil with the log). While this cache is meant to introduce you to a popular sliding hill, the cache will stay active all year round.
There is also a little something in the cache for the FTF.
