G-Man locations not in the Prima guide

[IonizeMyAtoms]

So far I've seen him twice: one at the end of Water Hazard and once at the beginning of Highway 17. In the second house look through the binocular thing and you can see someone from the resistance talking to him on the top florr of a building, it's practically only their silhouettes, but the briefcase gives him away.
Any one else find him in spots not mentioned in the guide?
Oh, and I took screens of where I saw him, if anyone wants to see. I'm in class right now so I'll post them when I get home.
