Yeah, it still seems a little convenient that Marty was able to make it to the projects so quickly, given that he had no idea where Rust was going to be before that phone call. I suppose we have to assume that Marty didn't stray too far from the biker bar when he drove off and that the projects also happened to be relatively close to the bar.

The fact that Rust had to improvise and ended up meeting up with Marty at an area other than their proposed meeting spot (and right on time, no less) still seems a bit too tidy.

This ultimately isn't a terribly big deal, though, especially given how enormously compelling and fascinating this show is. The finale is still among the most striking visual feats I've seen on television, and the fact that it is a genuine oner is pretty remarkable.
