I've heard or read about some structural damage to homes and some grocery stock thrown around the aisles, but I haven't heard anything about Dr. Grabow at all, so I assume no news is good news, and they are probably back at the shop turning out those pipes as usual. If anything got off kilter, I suspect the crafts people can repair it themselves. I feel they are a special group, being what is apparently the largest remaining U.S. factory making briar pipes. If anyone produces higher volume, they must be exporting them.
Incidentally, the last biggest Midwestern earthquakes were at a town that no longer exists, New Madrid, Missouri, in 1811. There were a series on that fault, two or three about a year apart, if I recall.
