Pedal-powered Roller Coaster
In Okayama, Japan, there's a new pedal-powered roller coaster.(!?) Here are some pics. It looks like it might be (#1) hard to pedal up the uphill parts, but also (#2) not that safe on the downhill parts! There isn't much of a cage around you, and if you look at picture no. 3, all you get is a little, teeny woven seatbelt -- not a big bar across your lap. It might be worth it to make people put in effort first, in order to get their thrill, but jeez... You might even say it defeats the whole purpose of an amusement park, which is where people get to be mindless and wasteful for fun.
