A Less Renowned Presidential Assassination

I'm old enough to have the indelible stamp of the moment when I heard that President Kennedy had been shot. I realize that more than one of our past presidents have been killed while in office. I just finished reading the most fascinating book, Manhunt: The 12-Day Chase for Lincoln's Killer by James L. Swanson.
I've come across a website that covers the assassination of another of our presidents, William McKinley. I haven't explored this in depth yet but it looks like a well-done site and has, no doubt, a number of fascinating details about what happened. Click here.
