Place these so guests don't litter.
In RollerCoaster Tycoon
Litter bins may be placed on any path except queue lines. These allow guests to throw trash away. After holding so much trash, they must be emptied by handymen.
In RollerCoaster Tycoon 2
Litter bins work exactly as they do in the original game. In addition to the standard style, Litter bins can come in different styles like mine-themed.
