I have a suggestion regarding the natatorium. The building is old and probably rotten through and through and is really not worth repairing. As far as I know, it has not been used by the public for many years — it just sits there, gradually rotting away.
Why not raze the structure, clean up the site to park-like standards and erect a very nice monument — a memorial to the World War I veterans to whom the natatorium is dedicated. It could be a user-friendly fountain with a wading pool or some other thing which would be attractive to visitors to the park, something that the public could use and which would make them happy that it is there.
