KANSAS CITY, Kan. (AP) – Kansas Speedway is increasing the police presence for this weekend’s NASCAR race after two explosions at the Boston Marathon left three dead and more than 170 wounded. Track president Pat Warren said fans attending the Truck Series race on Saturday and the Sprint Cup race on Sunday should budget more time for when they’re entering the facility. The speedway doesn’t plan to change its policy of allowing coolers into the track. Kansas Speedway hosted the second Cup race to be run after the attacks of Sept. 11, 2001, and Warren said the training and preparation of his staff under the most stringent security levels in U.S. history has helped ensure that safeguards will be in place for this weekend. Warren also said track officials have discussed a suicide that took place during last weekend’s race at Texas. He reiterated that firearms are not allowed at Kansas Speedway.
