Horatio D'Agostino, one of our Sunrise Tri Club members, had a fire at his business today.  KTBS report:   13 Shreveport Fire crews arrived at the Blue Collar Diner around 12:30 this afternoon to find the building full of smoke.  Firefighters got the blaze under control in about ten minutes. The diner wasn't open when the fire broke out. Officials say it probably started in the kitchen, but the cause is still under investigation.
