As we near the end of the first week in May, the warm weather has made its way east of the Mississippi. Mother's Day is this Sunday and the baseball season is already thirty games old. Clearly spring has arrived. Many of us mark the change in seasons based on certain annual events. For instance, if you grew up on Fifth Avenue, you might mark the spring season based on what's happening at Lincoln Center, The Guggenheim and The Met. If you were raised in the Bronx, it might be the first pitch on Opening Day. But there are some that swear that spring does not begin until you've had a mint julep and you can smell the freshly cut bluegrass as the horses exit the paddock to the tune of My Old Kentucky Home. This Saturday in Churchill Downs such pageantry will be on display at the 137th running of the Kentucky Derby.
