Just explored Fort Bannister with Charon and Dogmeat...a note: DO NOT take Dogmeat anywhere near that place...while its an awesome smorgasboard of Talon Merc killing goodness, its way too dangerous! A good place to get stealth boys, and ammo (that place is filled with laser ammo). But there's kind of a boss there, so depending on how you wanna play it, be careful (I personally used lots of traps; i.e. mines and stuff).
