Anyone remember the 3D Board game with little cars that moved along the board?

It was around durring the late 80s early 90s (I was in elementary school). I remember it having paths through the board, and the paths had little spaces that would go up/down hills and around corners. If you landed on a space that was going down hill when you let go the cars would continue down the hill. The board was mostly green and brown i think. It may have been a micro machines or monster truck game but i can't remember. This is killing me, if anyone remembers please let me know!!!|||DON KNOW THAT GAME BUT THE BEST RACING BOARD GAME WITH CARS IN FORMULA DE.....IF YOU DONT FING YOUR GAME TRY THIS ONE IT IS VERY FUN TO PLAY|||You can search it in the BoardGameGeek site... if it was a published board game, you'll find it there.
