It was a while ago, but on my fsecond playthrough I decided I would try to go around Primm rather than through it. As I was wandering around in the mountain, in the dark, with absolutly no idea where I was going, I came upon the Canyon Wreckage. Needless to say I had a moment. All that struff about Courier Six and the passage leading out to who-knows-where. Anyways I thought it was pretty damned cool.
Share your holy [censored] moments.
Well, I'm a gentleman, so I can't share my best [censored] moments... but one of my favs was when I was exploring across the Colorado river, just seeing what was down/over there along the river from Cottonwood on up... and I found a steep chute where you can get up out of the river bottom and climb over the rim, on the east side. I won't tell you what is up in that hidden rocky valley over there, but if you go to explore it, pack some serious heat.
