Atlanta Pride runs October 10–11 at Piedmont Park, and organizers released a dedicated mobile app this week. The app puts the schedule and performer information in one place, which is useful even for someone planning only a short visit.
The main festival is free; individual kickoff parties and other events may be ticketed. If you are going anywhere near Midtown this weekend, the scale of the event also matters for traffic and parking. The parade steps off Sunday at noon from the Civic Center MARTA station.
Do this: open the official event calendar and, if attending, download the app before arriving rather than relying on a last-minute search in the park.
