Rookie John King was the winner of the Nascar Camping World Truck Series NextEra Energy Resources 250.   You heard it  on Info Radio Friday night as he claimed victory in a green-white checkered flag finish.   This is only the fifth time for that kind of result in a Nascar Truck Series race.   There's more Nascar on Info Radio this weekend.   Tune in AM 1440 at 1 PM Saturday afternoon for Nationwide Series racing.   Sunday at noon it's the Daytona 500 on Info Radio, your auto racing station!
