The short and sweet on UE'ing Brook Run:

Brook Run is incredibly simple to get into. It's not about finding a way in...it's about choosing which side of the building you want to enter through. Even if every window wasn't broken, pretty much every outside door is unlocked, if mot propped open by debris. Sorry to any mods if this is violating the rules, but if you can see the building in plain sight, you can see at least three entrances.

Inside Brook Run is interesting. The most surpirising thing for me as a newbie is how fast a place can get dark. One room will be literally as bright as day, and 6 feet down a hallway, and you're in pitch black.

The place is torn to pieces. As said above, every window is broken, and if there's a room without windows, then there's probably some cieling tiles torn out. There's debris EVERYWHERE. Any room that hasn't been torn up, has the leftovers from some squatter. There's even a large reception desk that is pushed up on it's side and sticking into the ceiling.

There are a few neat rooms. There's one that's got a few huge xray machines, that are in near perfect condition. There's one dental chair in there that's old and cool...but for the most part, it's one torn up room after another.

I would definatly suggest this to anyone that's starting out. It's a pretty neat building...I think it'll be a while before I find something that rivals it's size, and maze like hallways. We spent four or so hours in there, and we're still not sure if we saw all of it.
