This kinda reminds me of something I heard on NPR once, that out in Arizona, at about 11:30am, there's this weird earth-rumbling drone that no one is sure what it is. The residents know exactly when it's going to happen...the govenment & the military have both investigated the phenomenon (I know that's not saying much) and cannot figure out what it is! Scientists and musicians (!) alike have confirmed that the drone, based on cycles per second, that it is an A flat. My opinion? God's taking his digeridoo lessons out where he was sure no one would complain!--Mbo
