I have been going to various web sites I bookmarked and trashing links to ones that have disappeared. I almost trashed this one as it looks broken. Glad I didn't!
Go to the site and find the "start" button - click it. There is nothing much on the new page WITH THE EXCEPTION of a garish button labeled "SITE NAVIGATOR." Click it and it changes into a huge drop down menu leading to a ton of great information, photos, and etc.
Here is the link:

Hope you enjoy it.
