[Fallout] Why is Megaton a town?

I remember visiting Megaton a while back and leaving near immediately. They have a nuclear bomb in the center of their town. I remember a mate of mine explaining why but it didn't make much sense back then.

And now re-visiting the place and seeing a miserable crater all I can think is, "Wow. You people were dumb. You people were so very, very dumb."

Unless I'm missing something here. Was there really all that good of a reason to build a city, which could be built *anywhere*, on top of a nuclear bomb?

It originally started as a waystation, but the town grew up around it, mostly for one reason.It's the crater. It offered pretty much the only shelter in the area (which was added to by the walls build of scrap) and served as a collection basin for water. With water being so scarce in the Wasteland, any water source you can find is worth hunkering down on, and as far as sources go... Megaton's water is relatively clean. 

And i mean... what are the alternatives? A derelict Aircraft Carrier in an irradiated, undrinkable bay surrounded by Super Mutants? A tower full of egotistical, wealthy bigots? A town populated entirely by cannibals? 

As far as shit places to live go, Megaton isn't that bad.
