I've been to Man o' War's grave. I went see it back in the 1990's at the Kentucky Horse Park, while I was there they also had A.P. Indy there (I think) as well, I got a picture taken with him.
The memorial statue they have of Man O' War is Beautiful, I hope to go back there again one day. I know I always say this to anyone (especially on this board) who has a horse that is descended of Big Red, but I envy you for having a Man O'War horse (a Man O' War descendant), you have a real treasure there. (Anyone who has a Man O' War horse has a treasure, in my opinion)
