I blew them up along side Caesars legion at the end of lonesome road, those mushroom clouds were fucking amazing

I literally did 4 separate playthroughs of the game just to get all 75 achievements.

I did the same, I only find sadness in the Mojave now, I've done every quest, explored every location, and earned every achievement. I have insurmountable wealth, an armory that would shame the NCR, and nothing left to do. Sometimes it's hard to be the best...

To be the best
We got to pass the test
We gotta make it all the way
To the top of the mountain
We can do it again!
To feel the high
We got to learn to fly
We got to take it to the sky
On the wings of an eagle!

You're the best in the world!
