and Sunshine Autos is good for raising some hell too. You can get to the upper floor and break out the glass, then crouch down and shoot stuff with your M4/Ruger, and they cant get you cause you're upstairs, they wont ever appear behind you and the helicopters cant get down to shoot you. Its easier than heck to jack Police/FBI/Army vehicles like that, just shoot out the driver and kill the people and jump down. You'll see what I mean when you do it. Fun stuff
