Yeah, I was thinking it was a cache in Alaska, too.
Not that it would be the first time. Friends of mine that have served in Alaska tell me that they find 'stuff' from time to time along the shorelines that don't belong to the US military.
Yep I have personally rendered safe old Jap and SIno soviet sea mines washed up on shore not to mention the horrific weather beacons er two....:o)
Lots of old ordnance and even some goodies miners left behind found all the time up there to BIB !
Hope yer well Sir....are ya back in or still out ?
