Okay, so if you see one of these things that look like a spiky
mooring ball, ya might want to give it some clearance and not try to attach to it.
An inert / practice positive buoyancy mine became untethered from the naval practice range in the
Puget Sound. Locals first spotted the floating mine Tuesday afternoon between Brownsville Marina and Bainbridge Island, a few miles away from the Navy’s Undersea Warfare Command base in Keyport, also known as “Torpedo Town,
USA.”
