Or sitting in the end grandstand at Avon Park Raceway in direct line of the zorsts of a pair of top fuel monsters. Your guts nearly vibrate onto the ground below.Like when unsilenced race cars pass by the grandstands and you can feel your lungs vibrate in your chest with all the glorious noise.
It's amazing how many people won't believe you when you tell them that as a Top Fueller (or two) pass you you can actually *feel* your internal organs moving due to the pressure waves from the exhausts.
