How do you get rid of the road blocks to San Ferrio on GTA San Andreas for PS2?

PS2 onlyYou cant, well I'm not to sure! But any how what i do is use the Lock felony state and Spawn(create) a Hydra, an American Fighter Jet. When u lock the Felony State Your Stars don't go up and U just use the Hydra to fly any way u want

Code For Locking Felony State(just Enter witout pausing etc.) oh one more thing Its For PS2 only

CIRCLE,RIGHT,CIRCLE,RIGHT,LEFT,SQUARE,TRIANGLE,UP

Code For Hydra

TRIANGLE,TRIANGLE,SQUARE,CIRCLE,X,L1,L1,DOWN,UP

Its great, i have'NT even done the first mission yet and I'm up in Las Venturas checking out the Chicks already(and the Ferraris)
