In order to waste time to allow money to accumulate without dealing with CJs eating
needs, simply press Triangle in front of the television in your hideout. His health will
remain constant, without him needing to eat. You can leave the PlayStation 2 idling in
this state to accumulate money easily.

Find a save point that is close to a betting shop. The one in the Montgomery are is
ideal because it is near to the save point where you have to do the four missions for
Catalina. Save your game, then go to the betting shop and bet all your money on a horse.
It takes awhile to enter the numbers, but is worth it because you can make a huge amount
of cash (especially if you bet on horses with odds of 10/1, 11/1, 12/1, etc.). It takes
roughly three to four minutes to bet the maximum amount of money, which is $9,999,995. You
will not win every time. When you lose, reload your last saved game. It is possible to get
$250,000,000 by betting your winnings of $30,000 to $700.000 to $2,000,000 to the maximum
bet.

Go to the bar near Ganton but do not go in. Instead, look around the bar and close to the
bridge will be a drink machine. Go up to it and press Triangle to pay $1 for a drink.

Go into Ryder's back yard (to the right of your house) in the Ganton area. There is a

Go to either Los Santos or Las Vatos airport. Go to the place that you would enter if
you had a pilot license. If you try to get in the gate, it will say you cannot unless you
have the license. Next to the gate is a small building. You will need a small car or any
type of bike (BMX, bike, motorcycles, etc.). Stand on top of it and jump on top of the
building. Jump off and you should see a fence (at Los Santos Airport). Climb the fence and
you will see a Dodo plane. Also, if you follow the runway east, you will see a small jet
that is unlocked. At Las Vatos, follow the same procedure. After you jump off of the
building, just walk around and look for a plane. Note: All but one of the aircraft
at San Fereno's airport are locked.

After using the "Fly plane without pilot license" trick at the Los Santos airport, go
forward you should see a Dodo airplane. Get in and take a right when inside the plane. Go
straight, then take a right at the runway. Go down it until you see a jet on the right. It
is not on the runway. You can get out of the Dodo and get in the jet. You can now fly the
jet wherever desired. However, be careful -- if you go out of your territory you will get
four stars and jets will shoot missiles at you. Try to dodge them if possible.

To get into the Los Santos airport without a pilots license go all the way south until
you reach a tunnel. On the south side of the tunnel, look along the fence line of the
airport. Notice how the sidewalk has an incline. Walk up the incline and climb up the
ledge where the bottom of the fence starts. Turn towards the ramp sign and jump across.
You should grab onto the sign. Then, climb up on top of it, turn towards the fence, and
jump. You should jump across and grab the fence. CJ will pull himself up and over, and you
will be in the airport.

To access Los Santos International airport early, get a large van and hop over the
fence where the guard tells you that you need a pilots license. You can also get any car
and hop over the fence around the corner from the guard. Once inside, you will have to hop
another fence, then you will find a Dodo. If you go a little further inside near the
runway, you will find a jet.

Walk up to the airport gate in San Fierro, touching it. Then, walk along the side of
the gate into the corner were the fence bends (keeping in contact with the gate) and walk
back into the middle of the gate. It will slide open. You must start in the middle and
walk to whichever side the gate will slide open to. For example, if the gates on the left,
walk to the left. If it does not work at first, keep trying.
