According to that rendering it doesn't look like there are chair back seats in any of the upper sections; north, south, east, or west.
And there's no way with the track still there that they'd be able to do away with the railing around the track. People would definitely fall into the lower sections. Lol
I've been a diehard Zips fan for so long that I have a lot of warm fuzzies associated with the JAR, but I can say objectively that the JAR utterly blows in every conceivable way.
