What started as a crack in the road yesterday has turned into a sinkhole the size of six football fields and it's not over yet. Construction equipment, tanks, trees and tractors have fallen into this massive hole located in Daisetta, Texas, a small town 50 miles northeast of Houston. The town, with a population of 1,000, was built on salt domes and experts believe the ground might have caved in because of the collapse of one of these old domes.
