Certainly am! I've just had my Tuesday evening fix of the ringing 
equivalent of a white knuckle ride!

St George's Cathedral bells are the only ring I know that can 
demonstrate a double Doppler effect: one from the bells turning full 
circle and the other from the tower sway.

It's getting to the stage where you need to take sea sickness tablets 
before ringing there!
