Firing an AK-47 at the Cu Chi range in Vietnam. Cu Chi is an area in Southern Vietnam outside Ho Chi Minh City, formerly Saigon, under which lies an incredibly vast network of tunnels. In these tunnels Vietnamese refugees and Viet Cong fighters hid from American bombing and lived for as long as 6 years, emerging only rarely. It has since been converted into a tourist atttraction and features tunnel hikes, tours, examples of traps and weapons recycling facilities used by the Viet Cong, and is, generally, a very interesting place. Try out the spider holes.
The firing range, which is incredibly loud, offers a variety of weapons ranging from bolt action standard-issue rifles to fully automatic assault rifles, and, for those with serious cash, belt fed machine guns. AK-47s, which were semi-automatic, were about 1 dollar per bullet to fire.
