With the kind permission of hamgran, here is Mr. Barkley 2.0!! Near this geocache lies the HMCS Ojibwa, a decommissioned Cold War era submarine, now turned museum.
You are looking for a small camouflaged tupperware container hidden near a trail on the east shore of Big Otter Creek. Essentially if you knew where the first Mr. Barkley cache was, you'll be able to find this one with no problems (no spoilers!). There is parking nearby and it shouldn't take you too long to find it if you know what you're looking for.
Muggles don't usually frequent this area but during Beachfest in the Summer, there will be a lot of them so use stealth if you intend to come around that time of year.
Happy 'caching!
