Clear signal: Boaters can operate U.S. Coast Guard's new foghorn system MLive.com
"Sensors in the lighthouse used to detect the presence of fog and would activate the signal automatically to guide ships into port.
However, the sensors began malfunctioning as they grew older and continually became covered in spider webs, Salzmann said.
To activate the fog signal, boaters must tune their marine radio to channel 79A and depress the microphone five times."
OK, this system is better than nothing at all.
But why can't the USCG clean off the spider webs?
Sup wit dat?
