Hmmm... could a Polercoaster be in the works for Nashville or maybe a Skyspire? Checkout both in the US Thrill Rides link in the next paragraph.
A poster on the Memphis forum posted a picture from the US Thrill Rides (
http://www.usthrillrides.com/) booth at the International Association of Amusement Parks and Attractions (IAAPA) 2015 Expo in Florida showing one of their Polercoasters with the indication of a Nashville, TN location.
Has anyone ever heard any mentioning of such a structure in Nashville? I think it would be cool. I'd even like the Skyspire simply because it's different than the typical Ferris wheel structures popping up everywhere. The Skyspire offer an opportunity for an observation deck and dining. Hey maybe the can do either a Polercoaster or Skyspire in the shape of a guitar... LOL
