 Because of its established motorsports roots, Hueytown was chosen as BMW Motorsport's initial North American base of operations before its first season with the International Motor Sports Association (IMSA) in 1975.Beginning in late 1991 residents of Hueytown, and other nearby communities, reported hearing a droning low frequency hum at irregular intervals.The bizarre noises momentarily gained national attention and were reported in "The New York Times" in April, 1992.
