A weekend traffic led Nebraska State troopers to a hefty drug bust. A pickup truck was pulled over for speeding on Interstate 80 in Seward County on Saturday afternoon. A state patrol drug dog alerted to the odor of drugs coming from the truck. A search of the vehicle turned up nearly 56 pounds of marijuana. Troopers say the pot was in duffel bags and luggage in the pickup bed. The driver, a 39 year old Idaho man, was arrested on drug charges.
