I'm not really sure why my brain decided to notice this, but it did. There is not a single musical instrument in the Fallout world. I find it unlikely that every instrument was destoyed in the war, but if they were, wouldn't you think that someone, in the span of 200 years, would've came up with some sort of make shift drum or horn? I know it's probably not everyone's first though that they should make a guitar right after a nuclear explosion, but I would think that there would have to be at least one instrument laying around somewhere.
