That setup was truly impressive. I like the long runs, and the size allows for multiple actions to occur at the same time. IIRC, the National Capital Trackers did a huge setup at York a few years ago - it was so long that they actually had some modules crossing underneath the others at one point.
Shameless plug: My club's (Pacific & Eastern) modular layout is featured in OGR run 320 which just came out. We take a different approach - there is a limited number of configurations by which our modules can be assembled. This makes for a less linear presentation and greater scenic opportunities, but it limits the flexibility and we aren't able to include "standard" modules that are built by others, nor can we do really long runs. I believe that each approach has its pros and cons.
Your club was wise and fortunate to record that video. Unfortunately, we don't have any video that I'm aware of, and many of our historical photos don't meet today's standards.
