Bull semen forces closure of interstate ramp

 Nashville, Tennessee - Canisters of bull semen caused quite a scare on the on-ramp to Interstate 65 South. The canisters fell off a Greyhound bus just before 6 a.m. as the bus traveled around the curve of the ramp just south of downtown Nashville. Fire and emergency crews were called to the scene amid reports of a foul odor. When they discovered four unmarked canisters with steam and an unpleasant odor coming from them, they shut down the on-ramp and called HAZMAT crews. Officials traced the containers to Greyhound after finding bus tickets on the ground.  The bus did not know it lost its load and had continued on. Authorities called Greyhound, who, after speaking with the driver the bus, determined the canisters to be filled with vials of frozen sperm packed in dry ice.  More
