I've been searching through machine tool manufacturers today, and stumbled across this town of 51,000 residents twice. What's going on here?
DMG Mori, which is headquartered in Hoffman, doesn't even rank big enough to show up. Ditto Renishaw USA.
It could be that this is just a manufacturing-heavy suburb of Chicago; I guess the name is just throwing me. Anyway, I'd be interested in visiting.
