Los Angeles Coliseum/Agriculture Park
Better known for being the site of the 1932 and 1984 Summer Olympics, the
Coliseum was built in 1923 on the site of an agricultural park which had been
the site of a one mile dirt oval (used 1903-1920's), and a 1/3 mile board track
for motorcycle racing in 1909. A 1/4 mile paved track was built inside
it at the end of World War II, with midget races held before crowds of 55,000.
A highly-banked board track was constructed there in 1948, but with slipping
attendance figures, plus a fatal accident on the 13th August 1948, racing was halted.
