"After completing a blind draw, it was determined that second place and $400 in prize money would go to Sheldon Silver of Toronto, Ontario, finishing with a bankroll of $117.50. Silver’s involvement in harness racing goes back over 30 years ago, when he was an owner, trainer and driver. He now considers himself a fan and takes pleasure in watching the simulcasting at Woodbine Racetrack."

He never had a winner driving and i am not a 100 percent sure but i think he only trained a horse called ARMSTEAD KELLY but he did go down for PETER swift when he had a possitive but he never touched one of SWIFTYS HORSES,   

There was a guy around 40 years ago and i did not know him or his name but he used to jump the fence to save 2 bucks when entering the track but around 10-20 times a year he made between 20-40 thousand dollar show bets and i always got involved and it was not a winning move for me as i dont recall him loosing one but i heard he lost huge on GUTS but i was not there that day,        This guy really irked me in the wrong way as he would pick up uneaten food or coffee or go into the garbage for food and i could not believe he was still alive with his life style but one day he climed the fence at FLAMBORO and security caught him and kicked him out and that day he went to bet a DAVE WALL 3 horse entry that missed the board and did not get the bet in i was told
