Wow, talk about some cool parents! No sandbox for this three-year-old boy! Oh, no! His father builds him a roller coaster in the back yard!

Jon Cain of Lancaster, Ohio built a 12-foot-high roller coaster. The ride is made of PVC tubing and concrete. It took 3 weeks to build and cost $700.

Now, before you start cringing at the thought of a "home made" coaster, Jon's wife, Natasha Cain said they did clear the construction plan with the city.
