THE CACHE IS NOT AT THE LISTED CO-ORDINATES.
THE REAL CO-ORDINATES ARE CONTAINED BELOW.
During the war against the North Vietnamese, the US military dropped a chemical defoliant called Agent Orange. The British had been using herbicides in Malaya for around ten years before the US-backed president Ngo Dinh Diem requested the Americans start dropping a defoliant to try to remove the bush and jungle hiding places the Communists were using very effectively. The chemical was produced by Monsanto and Dow Chemicals, and was contaminated with a highly toxic substance known by the four letter abbreviation TCDD (Tetrachlorodibenzodioxin). The toxins contained in Agent Orange are genotoxic and can cause cancer, birth defects and disabilities up to three generations after exposure. Over five million acres were sprayed with Agent Orange causing widespread devastation and health problems. One study by the National Toxicology Program linked Agent Orange exposure to four very serious health issues: soft-tissue sarcoma, non-Hodgkin's lymphoma, Hodgkin's lymphoma and chronic lymphocytic leukemia (CLL). Both the people and environment of Vietnam suffered greatly through the use of Agent Orange, and the effects are still being felt today.
In contrast, East of Nguyen Huu Tho Road can be found a large district that is said to be cleaner and greener than the rest of Ho Chi Minh City. Consisting of ten wards, this district is much larger than its numerical predecessor, District 6. At around 43 square kilometres and expanding rapidly (trying to find exact statistics results in zero finds!), District 7 is the new residential heart of the city. Boasting wide roads, expensive cafes and shops, and many schools, this is a popular place for both Vietnamese and Westerners to raise their families. Although there are many schools, the most famous are the Canadian International School and the Japanese School, which is located in block M9 on Tan Phu Street.

The cache is located in a green park in District 7 to symbolise Vietnam's recovery from the Agent Orange attacks. Please replace cache exactly as you found it and cover it up well. Let me know if the cache is waterlogged or the log needs replacing. Beware of muggles.
If you're interested in finding out more about the use of Agent Orange in Vietnam, the War Museum is very interesting. It also has a cache (GC3X8YF) for you to find.
