Thanks Jim,

I will look forward to the articles.  A lot of my older Bell friends will
also be interested.
When I attended St. John's Military Academy in Delafield, Wisconsin a friend
of mine and I broke into the basement of the cadet library The library had
once been the school gymnasium. In the basement was all of the DC generating
equipment the school had used before AC came to the small town.  I am
wondering if the equipment has been scrapped or still there.

The DC installation for the Bismarck Hotel in Chicago was still there about
10 years ago when the hotel closed.  Not sure what happened to the building.
The owners had spent approximately 2 million updating the hotel and making
one room out of every two.
Sadly, in the process they also destroyed most of the art deco decor that
was the charm of the place.

Some might look up the history of the Baker Hotel in St. Charles, IL.  The
place is still powered by a dam next to the hotel on the Fox River.
The hotel also has a beautiful lighted glass dance floor and a huge built in
pipe organ.

I think they have turned it into a retirement home.  

Best,
Don
