Wait, are you talking about building the whole track out of clear?
… and I am still thinking about how to do this flying Santa monorail. Clear 1x2x2 panels might work as long as the span between supports is not too great but then there is the pesky problem of turns … unless we create robotic turntables, hidden inside a building at each end of a long straight track. The turntable could rotate Santa and the reindeer around so they face forward and travel down the same long track that brought them into the building. 🙂
