Greeted me at the gate this morning as usual. Good appetite. Had him out Sunday no issues. Not lame, no colic. Went out back in the afternoon and he was down and already gone. No Truama or injuries. Tracks in mud indictes he standing still, laid down and died. Heart maybe, was in his 20s. Best one i ever had the pleasure to work with. Always ready to please and great attitude. We did alot of programs at schools the kids just loved him but I think he loved them even more. We traveled many miles together. At 18 hands and 2100 lbs he was a big boy. Good speed Frosty. You will be missed buddy.
