Do you know about the famous 'Sky door'? I have found a way to enter it!

Finding the sky door-

If you don't use the 'jet pack' as stated in the requirements and go high up above the cluckin bell in fort Carson-there you will find an Enex marker or whatever those yellow arrows that make you go into a house called.

Entering-

This definitely needs a 'jet pack. First you must position yourself next to the cluckin bell in fort carson-to the east somewhere above the road passing exactly next to the cluckin bell. Next active the 'jet pack' while on foot and use it to go directly up-it will only work if the program you used for the 'jet pack' leaves you standing in mid air (this is why i like crazy trainer so best is to go with it) now gain height and keep an eye out for the yellow arrow. when you see it fly to it and if all goes well you should get in a house.

The House-

The first thing I noticed is that unlike any other hidden interior, the walls, the furniture, the roof and everything has good collisions. This house is quite curious, there is a pistol pick up in the first room, the famous skateboard weapon in a room on the second floor and a pistol in the last one. Also there's is a man in black who fights you as soon as he sees you and for some reason though probably a glitch doesn't bleed when killed.

There are also pics of two of your girlfriends one of them with a man much like the one in the last room.

You can carry things around as in burglary missions but no house has so many stuff to take : 2 big tvs and 2 small ones, a radio a Hi-fi, a DVD player or something and a glitchy microwave which explains why those in the cluckin bell show the wall tiles as the microwave glass, they show anything that is behind them. Notice also the glitch which happens as a reflection on the floor which shows everything in all floors of the house as if there were no roof.
