"A trailer carrying 26 alligator carcasses to a processing plant overturned on a Fort Lauderdale highway (year unknown). The carcasses, which weighed about 10,000 pounds were put on a flatbed truck and taken to the processing plant."
TruckSpills.com, like its name clearly states, is a website dedicated to documenting things that have spilt out of overturned trucks. Some of the weirder things include alligator (above), glue, live chicken, and ... cocaine!
Oh, and there's this: a 8,000 liter (2,113 gallon) Sunny D spill (though it's not from a truck)
