Grass
Grass Land is the most common land surface in the RollerCoaster Tycoon series. Over time, the grass may grow weeds, which can be removed by mowing or clicking on the area with the land tool. In RollerCoaster Tycoon 1 and 2, handymen may mow the grass. In RCT1, grass is by far the most expensive surface, costing 3 times as much as dirt, sand, or gravel.
