The other day I overheard him talk about the 'Manhattan Nuclear Zone', so I've been trying to find all of Xander 99-40's (Bounty Tracker dude) random dialogue to glean some more insights into possible areas in the Solar System. Does such information exist or do I have to spend a few nights hanging around with the guy?

This is all they have so far:

During the beta someone on reddit posted a series of posts where he transcribed all the tower dialog. Dammed if I can find it though. Maybe someone with better search-fu (or not on a phone ATM).

I found this one, but it doesn't have anything from Xander (neither Part 1 nor Part 2)

Thanks for the help guys, I guess Xander and I are going to become good friends some time soon.

In the past few months I've found myself looking for dialogue transcripts that I thought I remembered for The Speaker and Xûr but I always have trouble finding them. Search-fu fail.
