SOUTH FORSYTH — Americans will spend thousands of dollars this week getting ready for July Fourth celebrations. While most will likely take in a free local fireworks display or parade, such as the city of Cumming’s at 9:30 p.m. Thursday and 10 a.m. Friday, respectively, many will also spend money on at least one family cook-out or other outdoor meal. According to a survey by the National Retail Federation, more than 152 million consumers, nearly two-thirds of those celebrating the nation’s birthday this year, will celebrate with a cook-out, barbecue or picnic.
