I found a minor unmarked location that isn't in the Wiki, I thought they'd all been found. To get to it fast travel to Camp Forlorn Hope, go round the right hand side of the tent you are facing, follow the path down to the river, swim across and go north. Full details http://fallout.wikia.com/wiki/Small_Lakelurk_Cave.

And, probably everyone knows this but it was new to me, it's worth shooting the hood of the truck next to the explosives crate at Powder Gangers West if you like things that go bang. Just don't be too close.

Yeah, I've found that before. I think it's mentioned in a note in the wiki description for Deathclaw promontory, but not it's own page I guess.

Nice.
Good find. It's new to me so I'll roll on over there and do a "check-it-out thing".
:tops:

Darn, you're right. I checked things but it didn't occur to me to check that.

Still nice to have it's own page tho.
