From Brad, our Boston correspondent:
One person was hospitalized after a sinkhole swallowed three cars in the South Deering neighborhood on the Southeast Side this morning.
Witnesses said the hole opened up around 5 a.m. at 9600 South Houston Avenue, quickly growing from about 20 feet to about 40 feet. First two cars slid in, then a third as the hole widened, witnesses said. A fourth vehicle was towed from the edge as it was about to fall inside, witnesses said.
Merko Krivokuca was driving his silver pickup truck to work when the hole opened up and he drove down into it. He was taken to Northwestern Memorial Hospital for “a couple of scratches,” according to his father, Peter Krivokuca.
Krivokuca stared in disbelief at the hole as cleanup crews hovered around the area.
Alejandro Filerio said he heard what sounded like a car crash early this morning. He looked out the window and saw a white car and a gold SUV across the street. Figuring it was just a minor accident, he went back to bed.
An hour and a half later, Filerio, 30, stepped onto his porch and saw the giant hole.
Ola Oni said she was about to leave for work at 5 a.m. but had not gotten in her car yet when it suddenly fell into the hole.
“It could have happened to me, I am lucky, I’m happy,” Oni said. “In this kind of neighborhood, I don’t think this should happen.”
She gestured toward the hole. “Look at this, this neighborhood is in danger.”
The sinkhole opened up after a water main broke, according to Tom LaPorte, spokesman for the Water Department.
The heavy rain could have contributed to the break of the cast iron pipe that dates back to 1915, he said. Officials are looking at the age of the main as well as weather conditions.

and I still didn’t find the story of the girl who was riding with a bunch ahead of her and saw the ground getting soft, then her horse dropped in the ground and she got tossed off outside the sinkhole. They did get the horse out but he died as a result of the ordeal. this was in 2012. I found the rest while looking for her story there are probably more.
I had one form on the edge of my corn field 2 1/2 ft dia. and bottomless as far as we could tell, last Sept 2012. Our shallow well dropped out when it happened. We live in the finger lakes on top of a hill so its pretty strange but our farmer said there is another one as big as my kitchen table that popped open in town too. We jammed ours with different size rocks and filled in the top with dirt to keep it from eroding more soil away down the hole. Plowing this spring hasn’t shown any more collapse so far. I have always thought it would be interesting to plot them on a map and see if there is a pattern ! Like http://www.nydailynews.com/news/national/photos-harrisburg-pa-plauged-sinkholes-article-1.1253254 and then link it up to your list- Cool idea! Thanks for you gift of time, God bless! Caroline
