Nice job, Jeff. Really have to print and build one myself sometime.
The subject reminds me of something I came across online a while back. Google "Niagara Confluence" for some interesting results on an old power station on the Canadian side. Here's the first site I saw;
sleepycity | photography urban exploration | DIY Supervillain Hideout
Another good one;
Confluence: The Toronto Power Company Tailrace Tunnels, Niagara Falls | Pridian.net
There are also exploratory tours online of a couple of other decomissioned stations at Niagara. Really interesting reading and pictures.
