To Get to A Secret Place In Miami:

Well it's not a very secret place but select 'Take a Ride' on Main 
Menu and Choose Miami as your City then select a time of day and 
weather and if you want cops ON or OFF and also choose a Vehicle. 
Now choose Start Point Number 3 (the 3rd spot on the little Map).

Now at the beginning of Game, DO NOT turn down any of the 1st two 
turnings, go straight on until you see a Diagonal sort of Road. Turn 
right and go down the road until you get to some Traffic Lights. Carry 
on going across the road now you should see a Car Park on the right, 
but keep going ahead, then you will be going over a bridge.

Go over bridge and carry on down the road. BUT at the end is a Dead 
End! Now reverse or turn around Note: If you are reversing, keep 
looking to the right and if you turned around keep looking to the left!) 
then you will see a wide Tunnel, go through it. Turn Left and drive on 
until you get to a Mesh Fencing, run your Vehicle into it (it won't 
damage your vehicle) and it should fall down! Infront of you, there is 
a Little Motorhome. Turn left until you get to more Mesh Fencing and 
knock that down too. Now you are in the Secret Location!
