The entire school, pre-school all the way up to the 9th graders, went on a field trip to Pa Sak Cholasit Dam in Lop Buri and Saraburi provinces, about 3 hours on a train (after a 1-hour bus ride). Most of the kids had never been on a train. At the dam, the kids shopped, bought too many toys and candy, and a few went to the museum that had many of the lakes fish. There was more planned for the field trip but some logistical problems ended the trip early but everyone had a great time.
The creating the biggest reservoir in Central Thailand, the Pa Sak Cholasit Dam was constructed in 1989, the earth (soil)-filled dam with a clay core. The dam is a little over 3 miles long.
