Grant Park

Atlanta's oldest city park carries a steady, documented evening scene in its northern parking areas — window-down car cruising with a wide mix of guys, picking up after dark.

Know before you go: Georgia's public-indecency enforcement is real and Atlanta police do work the parks — keep everything in-car and discreet, and take it home. Piedmont Park's legendary scene, for the record, is mostly history now: lighting, construction and patrols ended its golden era, though the name still echoes.
