The Kentucky Speedway offered tickets to future NASCAR races to thousands of fans who missed Saturday’s Sprint Cup Series race because of massive traffic jams that ensnared them for hours outside the racetrack. The ticket offer came Monday as a top Kentucky state lawmaker called for legislative hearings and Gov. Steve Beshear said he’ll assemble a team to explore the cause of hours-long gridlock that tarnished what should have been a triumphant day for both the track and the state.
