So another few questions come to mind. Working with the mobility guys, are they friends of yours, or what led you to deal with them? It seems to me, in hindsight, to be a great idea to work with folks that have to come up with solutions every day that aren't off-the-shelf, and would also require appropriate power and methods for wiring. That, in itself, seems like quite the interesting backstory.
Wiring everything up - any snags they ran into, do they have small children to fit into those areas, are they simply not prone to any kind of claustrophobia, are they former circus people or really super bendy...getting into the few areas that the wife and I have gone, that seems like a lot of work in skeevy positions to me.
I remember seeing something in the past about the pole work - is that mounted solely on the deck? It kinda looks like there's something additional under there to stabilize it. Seems like just deck mounting would seriously stress the fiberglass, so to me, it seems like there would have to be more to it than that. I know one of your past poles utilized the tower for additional connection points, this one seems to be the first free-standing version.
What was the time frame that all this work took?
