GREEN POWER IS ARRIVING TO COASTER CRAZY! I have been working on this for about 2 weeks now and I am JUST finishing up the supports. This will be posted soon or in about a hour. Trust me its smooth and is a inverted coaster with my own made up element called the snake roll.
Dont worry, some people see pre-fabs as cheating, but I see them as a tool that you can mold as needed. Plop one down and add on to it for easy realistic looking supports if your short on time.
