Check Out These Backyard Homemade Roller Coasters!

I find it scary enough going on commercially built and inspected amusement park roller coasters, it'd be tough work trying to get me to go on one that uncle Al built that runs up the side of his shed and around the inflatable hot tub. Okay, the ones in this video aren't that bad, or tall, but they're certainly pretty epic for a backyard project!
