The G-Coaster, from Gravity Coaster (www.gravitycoaster.com), is a versatile downhill gravity vehicle specifically designed to run on grassy slopes. It provides a safe seat (no balancing required) and allows riders to "carve" down slopes, in much the same manner that skiers do. The G-Coaster can be fitted to the back of chairlift seats, or pulled by pomalifts, and operates off-road, so requires no costly alteration to the natural terrain.
