Can you give me proof?
My theory I posted yesterday, you were one of the one's I had hoped had seen it.

{135}{}{Oh... I didn't know we had an outpost up there. Anyway, the main base is off the coast of San Fran a ways.}
{137}{}{Well... How do we get there?}
{138}{}{By vertibird, of course. There's no other way, unless you have a ship. It's way too far to swim.}
This not only suggests that there are infact multiple outposts but that they may infact be large enough to be self sustaining, unless there is some other way that a young Enclave trooper doesn't even know the location of their capital. However, in the context of the Enclave appearing again I believe that all these outposts will have regrouped at Navarro, there still probably won't have been many of them and it would help account for the numbers present in Fallout 3.
