Getting Easy Money
Pick "Turf War." Then go to loot grab. Then pick the forest level, go below that and pick the "Cookie Toss" mission. When you get your "contraband" Since there are only three places where the "contraband" will be. Go up the hill in front of where you pick up the stolen goodies. There should be a dirt path, follow that, until you get to where you have to drop the "contraband" off. Then jump off making sure that you jump over the red or blue flare. That's how you save money!

Waterfall Tunnel
I found a cool tunnel that at the end, you fly through and out of a waterfall. First start the game in Joy Rider,(2 player). Play in the Forest. When you start, in front of you is a river. Go right, and follow the river until you get to a waterfall. When you are looking directly at the waterfall, you will see a path that leeds up to the top of the waterfall. Go up that path. When you get to the top, keep following the path until you get to the end of what looks like a forest like half pipe. To your right will be 2 bridges. Go to the second one, the one that does not have a roof over it. Drive across the bridge and right when you get across, in the top left hand part of your screen, there will be a pretty good sized hill. On the other side of ther hill, which is not the far at all, there is the tunnel. Go into it. You will start to go down, then up, and make a few turns. But at the end, is where you FLY OF A WATERFALL!!!!( a neat little trick is to have 2 players, and one of them watches the front of the waterfall while the other flies out, and you can see a car suddenly shoot out of the waterfall, it is pretty cool.

Desert level Hidden area
Go to the bottom of the staircase (has a stone bridge over it), drive up the staircase, make a sharp left after passing under the stone bridge. continue around to the left and climb the hill. You should be able to drive up and on top of the stone bridge, use a strong car. Cross the bridge, Carefully! You will enter a small dune area and a trench that goes pretty far. It will drop you into the snake like dune area.
Another cool spot is the Massive jump.
It is located by the telephone poles, up against the canyon walls. The best way to describe the area is that its almost the complete opposite side of the world that you start on in free ride mode.
There is a hidden road that will climb pretty high up, follow this to a huge pit area with a big ass jump in it.
