Opponents to the beverage tax stood and sat wearing blue shirts, holding signs that read, “Don’t Tax Our Groceries”, “Protect Our Jobs”, and “Stop Taxing Working Families”. They were mixed with tax supporters in red shirts with signs that read “Fight to Keep Our Communities Healthy”. Support and opposition went back and forth among the more than 150 people who signed up to testify at a downtown public hearing Monday morning. It lasted well beyond its scheduled 11:00 a.m. wrap time, extending almost four hours.
