Ok, we got some interesting replies, and one good research job on the first go-round, so let's see if anyone wants to play again.

1. One horse sired offspring that won 50% of all U.S. throroughbred horse races between 1865 and 1880. Who was he?

2. The Louisville Jockey Club, which created and sanctioned the KY Derby, was formed in what year, and founded by whom?

3. Who was the first Triple Crown winner, and when?

I'm a bit surprised we didn't get responses from Allan Myers (Mr. KY Derby) and Gene Trimble on the first contest. Maybe they didn't see it!
