Thanks Nemo...I've turned down all companions so far, left Rex somewhere to get old and die

I haven't been into New Vegas (hence the comment about the passport and not using it yet)

I have the hunter's rifle and hunter's handgun.Strangely, the handgun has an awesome sniper sight on it and packs a wallop, compared to the rifle version.
The incinerator has to be my favorite weapon so far, lighting things up and then having them talk to you while they're burning and dying is quite satisfying.
