It’s Labor Day weekend, which means that it’s the last opportunity to get that summer road trip in that you’ve been planning. Atlanta United will be on the road as well: it’s at D.C. United on Sunday night to get its first taste of Audi Field and hopefully sweep the three-match season series between the two clubs. With the holiday, don’t be surprised to see a heavy presence of Atlanta fans making the trip to our nation’s capital in hopes of seeing Tata’s crew win its league-high ninth away match and extend its unbeaten streak to eight in a row.
