Now obviously, Tennpenny Tower is going to get rushed. I think they would also want to head over to GNR radio to try and persuade Three-Dog to let them send a message over the air. After all, Three-Dog is pro-ghoul, and anti-feral ghoul.
They might also swing past Paradise Falls, due to their being an enslaved ghoul.
For guns and ammo, if they have the manpower, I suggest raiding Brotherhood of Steel Outcast posts, to grab some power armor, gattling lasers and other weaponry.
What do you guys think?
