Just like to point out, since the Wrecked Seatub seems to be utterly vacant, that just North of the Seatub entrance there is a path up through the rocks. You can see it easiest by a Mirelurk creeping up along the first section, a part coming out of the water. From there you go north until you see a faint pathway heading up to the west.Eventually the ground will get rockier, then you turn North again, you'll find a skeleton, two frag mines, a scoped magnum, a combat knife, some chems and two ammo boxes.
If this place is mentioned somewhere else, could we add it to this entry to, please? As it seems the closest and most reasonable place to point it out from!
