On July 17, 1987, a sudden flash flood swept a bus full of children away at a low water crossing. The incident occurred near the town of Comfort, Texas, which lies about northwest of San Antonio. At the time, the Pot O' Gold Ranch, which is situated on the south side of the river about two miles southwest of Comfort, was hosting a church camp, with over 300 children from various churches attending. On the night of July 16 and into the morning of the 17th, almost of rain had fallen across the Texas hill country to the north, triggering immense flooding on the Guadalupe River. The camp was scheduled to end on the 17th and the children were to be headed home later that day, but camp supervisors at the ranch decided to evacuate the children early that morning before it rose too high. At around 9am that morning, the children were loaded into buses and the buses were directed to a low water crossing.
