A friend and I were on our way from LS to Chiliad peak while driving our Merryweather Mesas just to pass time, and along the way we decided to stop in Paleto Bay to stock up on ammo and repair our vehicles. My friend for whatever reason, decided to play chicken with a passing train in the trainyard and somehow got shot up into the air and straight into a "hidden" room at the top of the building. It's not really hidden, but it was easily overlooked by both of us, and I'm sure by many other players. Anyway, the roof of this building has a main room at the top with a second room below it and a gated room at ground level with a nice hidey-hole in the back. He suggested we make this gem of an area our base, so we collected the local helo and put it on the roof, and the bulldozer to make as an easy way up. Since there's no direct way for the cops to get to you, it's safe as long as you stay away from the windows, and you can use passing trains in the back for a quick getaway. We spent ours running around this "base" taking on the police, and it was a blast. The whole experience reminded me of being a kid making up fun games with friends. If anyone is open for something different and has a friend to goof around with, I highley recommend making up your own games with this place. Thanks for taking the time to read. I'll edit with pics soon.
*edit* Sorry, didn't notice the rules at first. Can be done solo, but I recommend doing it with others. Doesn't require money, and isn't a mod or glitch. Oh, and it doesn't screw over anyone else, since it's so far out of the way of randoms.
This is the front of the building. The main room is at the top with the two windows, and the side room is the window on the right. You can get up there a few ways, but I found the quickest to be from jumping onto the a/c unit on the wall next to the bulldozer.
Here's a view from the right. You can see the window you hop in to get to the main room and also the ladder used to reach the roof.
Here's a view inside the lower room.
A view of the main room.
The gated room on the street. While in the "base" most of the police will congregate in here for some reason.
The hidey-hole that's just big enough for a person.
The roof has just enough room for a helo. There's a small water tower behind the camera that'll eat the rotors if you get too close. (Side-note: there's a "guard tower" in the back of the photo.)
To the south of the "base" is another "guard tower".
There's so much more here and I didn't want to make the post too long, and sorry for how long it already is. Plus, finding things on your own is part of the fun. Don't know how to hide things with spoilers. If it's a bother, let me know how and I'll be happy to edit. Also, hope this helps give someone off-the-wall ideas for fun.
