In Nov 2010 we tried out the new roller-coaster style zipline at Hidden Worlds called "Avatar." It seemed more like an in-the-works prototype but something with great potential. Here's how it was back in 2010: A steep drop at the start (surprise!), another shorter drop and a skim above a gravel parking lot (ugly), through a black plastic "tunnel" (cheap) and a too-jerky swirl down into the water. We are wondering if they have improved it in any way since then? We also heard Xplor was going to do one of their own (via an employee there), but have heard nothing since. Thanks!
