Andale?
Spill it!!! You got us all in suspense. I have not seen any Little Lamplight children outside of Little Lamplight anywhere but Big Town (who are exiles) and Paradise Falls.
Like stated before, this is the spoilers board for people who have beaten the game or dont mind the hints or obvious statements that lay out the game.
OK Ok
DO NOT READ IF YOU WISH TO DISCOVER ON OWN
Near fort Independence there is Andale. "The BEST place to live, BETTER than Rockville"
To find it travel out of the fenced gate of Fort Independence and follow the road until you reach a trailer something on a concrete slab, there is a cardbard box mat bed inside so once you see that you should see the rocket ship landmark where Andale is at.
Locate the at rocket ship at the top of the hill and travel there. Start talking to the people.
MORE than you should know:

The children there, unlike Paradise Falls
(STOP if you have not found the FALLS yet)
(I just found it this weekend quite by accident traveling to the PITT and I got through Broken Steel already)
The children of Andale, unlike those at Paradise Falls, will not run to Little Lamplight on their own, presumably, their packages are set for Andale only(thus my interest of locking them in via "close gate "at the Lamp.)
HMMmm...upon reading THIS, I found there is another way to save the kids...
