There's power armor lying around everywhere and yet the people of places like Diamond Shitty don't bother making off with them and instead sit around doing bugger all. You could say that about all those weapons in abandoned prewar safes and other containers lying around unopened. Yes I know the Institute is too incompetent to do anything right including wiping their asses I'm sure. I just don't believe Boston could look like this after 200 years with no hint of progress besides Diamond Shitty while people trip over dusty skeletons to get to a diner table to eat next to another dusty skeleton. Lets not for get some places even have super mutants next door to feral ghouls and raiders yet no one has killed each other. Sorry if I come off as a dick but this is your everyday theme park with wacky things going on that shouldn't make any sense logically.
