“Some days, it’s a good day to have breakfast,” says Thomas Builds-the-Fire in the wonderful “Smoke Signals.” And one of those days is Sept. 11, when the Environmental Professionals Network holds its next breakfast program (which you can say has to do with smoke in that it will look at how to reduce it). Called “Achieving Clean Energy Goals: Meeting Technical and Policy Challenges,” the program features a panel discussion by experts from Ohio State and the utility industry. And, as always, breakfast. Register by Sept. 6. (In fact, according to CFAES’s science-based Chow Line nutrition column, it’s always a good day to have breakfast if you can.)
