Thanks to Gerry Riskin of the Edge Group and author of Amazing Firms, Amazing Practices for passing this along.
Recently, high winds went whipping through downtown Indianapolis, blowing windows out of buildings and generally making a mess of things. Part of the mess was documents from two law firms, which were scattered throughout the downtown area. Most of the papers, which included at least one will, have been recovered. Other businesses lost documents, some of which contained pretty sensitive personal information.
Whether it's personal or privileged, you just don't want them blowing around town.
