Churchill Downs has tightened security for the Kentucky Derby following the Boston Marathon bombings and asks spectators to be observant of their surroundings during next month's races.
The Kentucky Derby and Kentucky Oaks are expected to draw close to 250,000 fans on May 3-4. The Derby will be the nation's largest sports event since the marathon.
Churchill Downs had announced security policies for the Derby and Oaks last Friday. But after meeting with law enforcement officials following Monday's blasts that killed three and injured more than 170, the track strengthened its procedures.
Coolers, cans, fireworks and camcorders are among the items banned from the infield. Fans will also be subjected to an electronic wand search and are encouraged to watch for unusual and suspicious behavior.
