I am glad you asked this, because I spent a long time several months, ago, trying to find something about this on 'The LagoonPark' site. This gave me a chance or the inclination to look, again. Still nothing on the site, but I called the corporation and they have just printed a new book with much more history of Lagoon. No guarantees, but I bought the book and should receive it in a week or so. I'm sure someone out there has a picture, but I'm hoping there will be one in this book.
Thanks, Alta
