"Golden Track" is the most unique set of coasters I've ever seen...
It's a slot track, sort of.
From their website:Clear your head, focus on those rails and hold that glass steady. On your marks... Get set... GO!!! These drive down memory lane coasters can link with each other forming a slot car race track.
