It's a smallish small cache, log only, bring a writing implement, not much room for swag. You'll most likely need a TOTT to retrieve this one. Don't get crazy replacing it, though. Position it far enough "..." to be hard for Muggles to see, but not so far that the next cacher calls you rude names.
Also, it might be interesting to note in your log whether the gate was, wait for it ... open or closed!
