of the camp, on more than one occasion the American guards had to use billy clubs to "quell disorderly prisoners as they were prone to pro-Nazi uprisings." Nothing remains of the camp and in 1989 the site of the Bull Farm became the present-day Quail Creek retirement development center. In 1948, R. Keith Walden relocated his Farmers Investment Company (FICO) from California to Arizona and purchased the Continental Farm to use as his headquarters. In the 1950s, Keith grew concerned that competition from synthetic fibers would threaten the cotton market and in 1965 he transitioned his farming operation to pecans as an alternative crop. Keith chose pecans because of their compatibility with the climate of the Sonoran Desert. FICO is still owned by the Walden family and their orchards combine to form the largest pecan grove in the world. Today, several of the old adobe homes in Continental are still in use. The old Continental School was replaced in the 1990s by a new facility located about one mile to the east. The old school was refurbished and now serves as the Continental Community Center. The Continental Cemetery is located northeast of the old school, and is now completely surrounded by the Madera Reserve subdivision. Considered to be a holy site by local Indians, the cemetery has been in use since 1903, and the oldest marked grave is from 1918.
