Go to checkpoint 6 -- it is easiest to do a 180 at the start line. Go straight over the tracks over the mountains and find the little town that is out a bit.
Immediately after you go through checkpoint 6, keep following the trail. You will see a bridge once you go Down the hill. Go over the bridge. To the Right is a fenced in area with a oil tanker truck in front of the entrance. This is immediately before you go through checkpoint 7. The cash box is over to the Right side of the fenced in area.
In the last turn before finish line run, go straight into water. A box of money containing $1495 is under water by the back edge of the pond.
Go under the train trestle in the middle of the pond to find $1500. Note: This works only once.
Off on the Right is a small island just offshore. On top the island is a chest.
Look inside a Porta-Pot up on a hill on Left between gates 5 and 6, next to the tents to get $653.
Go straight when you pass through checkpoint 5. After a little driving you will reach an aircraft hanger with a jet inside. In the corner of the hanger is a box of cash.
After checkpoint 2, make the jump. Instead of making the Right turn to checkpoint 3, turn Left. You will enter another fenced in area with dirt mounds. A box containing $2242 is in this area besides a mound of dirt.
Just before you reach checkpoint 7, stop in the water. Turn Left and stay in water. Keep to the Left at the fork. After this, there is a small rock jetty to your Left. In the small pool beside it is a box of money with a little over $1400.
When starting, go over to the beached tanker boat to the Right, and drive around on the water side. You can find another chest in the side hull, with $666.
From the starting line, turn Left off the track and drive straight until you reach a highway. Turn Right, stay off the road about 40 yards, but just below the hill that runs along the highway. There should be a big dip next to the road within a few hundred yards. Down in the lowest part of the dip is a box with $907. If you are just flying Down the side of the road you will miss the box.
Note: All hidden money amounts vary depending on how much the race is worth.
If you cannot see well when racing at night, just turn the Brightness up on your monitor.
