You've been frozen a long time, pal [I'm going to speak to you like you're actually the character you play as in Fallout 4 because who else doesn't feel like their wasteland explorer, right?]. And since you've been on ice, a lot of amazing things have happened.
Oh, you need an example? Well, how about the baseball bat that won the World Series in 2076. What do you mean you don't care about the 2076 World Series because you were a frozen hot dog? Get that out of your mind immediately because this bat is special, my friend.
You see that? You see how far these guys go? A disembodied crowd even cheers for you! And what's better than a bunch of ghosts from the Old World cheering for you after you kill a Super Mutant or a Mirelurk? Just find this bat and let it rip my friend. It'll be the most fun you've had in a long, long time.
If you have trouble finding this bad boy, check out Jamaica Plain. I've left a picture of the Pip-Boy map and the location above. Let me know what you think of the thing. But you already know how I feel, I love it! There's nothing better than the sound of the crack of the bat against the skull of a raider, am I right ladies?
