It's a peaceful settlement of post-nuclear survivors, and it sticks out like a sore thumb. Rivet City is a gigantic American aircraft carrier that's split in two. So, if you've gotten anywhere at all in the main quest, you've already found Rivet City, and you can teleport there instantly. Rivet City is an impossible location to miss during the main quest, since you'll need to find it relatively early in your quest. To undertake the quest, you'll need to head to Rivet City.
If you're an American history nut (like the author of this guide, for instance), then this side quest might be more up your alley than any other in the game.
