The stage collapse before a Sugarland concert was a late wake-up call for people who manage large public venues like concert grounds and football stadiums. Venue managers gathered in Norman, Okla., Tuesday and Wednesday, March 5-6, with weather forecasters and revealed there have been many close calls. (AP Photo/Darron Cummings, File)
