Enjoy Kentucky Derby Day at the Loring-Greenough House by participating in a hat parade, sipping on a custom Jamaica Plain cocktail and supporting JP Centre/South Main Streets this Sunday. And, of course, watch the big race. It will be a stylish soirée with all proceeds going to JP Centre/South Main Streets (JPCSMS) programs and events. Dressing up in seersucker suits, donning bowties and ridiculous over-the-top derby hats is strongly encouraged. The drink of the day will be the JP Julep featuring bourbon supplied by Roxbury's Bully Boy Distillers.
