The guys over at CougCenter do a Sporcle Quiz about once a week and I thought it would be fun to do a horse racing version.
The first quiz challenges you to see how many of the 18 horses you can name that have won 2/3rds of the Triple Crown in a year since Affirmed. Any 2/3rds will do - Derby+Preakness, Derby+Belmont, or Preakness+Belmont. Just type in the horse's name and the program will populate it in the right spot (if it's a correct guess). The years are provided as a hint.
You have 10 minutes to complete the quiz once you begin.
