This has to be the best dad ever. He decided to build a roller coaster in the backyard of his home! This is actually the 5th coaster he has built. He really knows what he's doing. This backyard coaster has 480 feet of tracks, reaches speeds of up to 22 miles per hour, has a 20 foot initial drop, and took only 3 months to build. I always wanted to have the Demon Drop in my backyard. Could you imagine? Would your parents eventually take it away because you "haven't ridden that Demon Drop in months". I think my most exciting coaster like toy growing up was my sit and spin. Whoo.
