St-Louis Facts

The Gateway Arch was built as two separate legs measured to meet precisely at the top. On October 28, 1965, the morning sun expanded the south leg. The last piece would not fit. Workers ran fire hoses to the top and soaked the steel until it shrank. Hydraulic jacks applied 450 tons of force, and the final section slid in.

Bigfoot is widely called the first monster truck, and it began as Bob Chandler's 1974 Ford F-250. He kept breaking it off road, and local shops did not stock the parts, so he opened a 4x4 shop. In 1981 he drove it over junk cars in a field and filmed the run, and in 1983 more than 68,000 fans packed the Pontiac Silverdome to watch Bigfoot. Bigfoot trucks still tour arenas today.
