There was a sink-hole in St. Paul this-morning.
Ever since I heard this story about a woman who fell through a grate in Manhattan, I've been worried about sidewalk grates. I just can't function if I have to worry about whole sidewalks, too!
Someone I know sent me a PDF file that had some pictures. This is a really huge hole. When I first heard about it, I was thinking man-hole cover size, not SUV size. Anyway, check out the PDF.
