I Should Build a Roller Coaster

This is the earliest pic I could find of this project - August 19th, 2011.I saw some of the first pvc backyard roller coasters kids were making on YouTube and thought they were extremely cool. I made this little test track from scraps I already had in the garage. This project started out as a backyard coaster ride for my kids back at my old house. We had a much bigger yard in the old house.
