Scott Shaw runs Fishbowl, a company that helps restaurants maintain contact with their customers.  He was born in Miami but he spent several years enthusiastically living in Texas.  While he was there he invented a barbecue detector that could be mounted on a car’s dashboard like a radar detector.   In fact it was actually an old radar detector that Scott had modified so you could “set” the detector for hickory or mesquite when you drove down Farm to Market roads looking for great barbecues.  It didn’t actually work for radar and it was incapable of detecting a barbecue pit.  Technology has caught up with Scott’s idea and now Texas Monthly has an iPhone application that uses GPS to direct hungry people to great barbecue places across the state.  Scott is the Lone Star Arthur C. Clarke, envisioning a better future of napkins, cold beer and butcher paper.  Texas Monthly publishes a great annual barbecue issue and you need to have one of their readers in the front seat with you, discussing the comparative virtues of Lockhart, Texas’ two barbecue joints.
