Blast from the past, potentially

Check this out: a UXB got some people at work a couple hours off work today. (Not me, though. I got to continue working normally.)

This is the second time since Fall 2009 that leftovers from WW2 have had a direct impact on me. Another time, my train from Nürnberg to Regensburg had to be re-routed because of a bomb dug up at a construction site near the railway. Has it ever happened to you?
