the sneeze , i noticed all of our tour guides began to crouch down , face almost to the dirt , and begin talking very quietly , one motioned for my wife and i to do the same , so we did , he bowed his head and put his hands to his face momentarily to show what they did , and boy , mr. heckerman laughed , when it came , we knew , we were 200 feet away and it still was the loudest sneeze ive ever heard , louder than i thought i could hear- even at that distance .
