Swing sets and jungle gyms are good enough for your average back yard. But if you want to go extreme you need to build your own backyard roller coaster.

This impressive offering uses PVC pipe for the rails. At its tallest it stands 12 feet, using pressure treated 4×4 lumber as the supports. Pressure treated spacers span the tracks, with the uprights — which are cemented in place — in the center.

These People have done some Impressive work! Personally, I would trust my own Workmanship, over a Strangers... At a Theme Park or anywhere else... But, I would definitely build in some very good security features. Seat Belts and Roll Cage etc. Check out the links below for more Videos...
