Here’s a new stamp for the blog. Unfortunately I can’t tell you much about it that isn’t right there on the tin. Don Plantz Concrete, LLC, has no Web site that I can find, but OpenCorporates says it was incorporated in 2018 in East Lansing, and it seems to still be active.

This stamp is on the driveway of a house on the west side of Rumsey Avenue’s northernmost block.
