Final is on the ground and hidden in plain sight, has a bag with a log in it inside, there is also a container locked up that was the original cache, but seeing as you can't get to it except maybe in the summer, it is taken out of service.
You can also get a bonus log by e-mailing us the location of the mural that has Lancelot in it. Via Groundspeak rules though, you must find the final and sign the log book before you can claim the bonus find.
