Name/Location: E-092 Air Defense Company 20mm Gun 2nd Platoon. Near the entrance, you can still see where tanks used to be parked. The once-mysterious tunnel entrance was overgrown with grass and weeds, but has been specially cleared for this event—it's easier to find now! The impressive tunnel makes us feel so small; the area is cool and perfect for taking elegant silhouette photos. Strike various poses and take pictures as you like!
