ok get into a big fat pursiut, the more police the better, but if u got a chopper on the look out then ur in trouble.
once u got some followers, drive to the bus depot, it is close to a police station and looks like a big glass building. head inside the bilding, smashing through the glass, now look for 2 rapms inside the building, head up one of them.
at the top, there is a glass wall, drive slowly through it (fast enough to smash it) (this gets u damage to property)...
now drive ontop of the row of buses just outside the glass wall you just smashed. drive along the top of the buses and stop at the end but make sure your nose of the car sticks out so the police can see you.
while your there, the police cars are down below ramming themselves into the busses and smashing themselves up, hang here for a few minutes...i was there for so long that i went to get some lunch and changed of AV and watched some TV.
be carreful coz if ur unlucky one random police car might try to come up. if so just drive him off the buses and blow up a few cars below.
i racked up 160 000 bounty here. once u need to evade, just reverse off the buses back to the ramps and stick inside but up where the police wont get you.
HAVE FUN !!!
