In a really peculiar coincidence,  on Tuesday I was taking the last supers
from a yard of bees that is about 100 yards (meters?) from a gas well that
was being serviced. This field is a sour gas field, and there was a mild
smell of H2S carried to us on the wind which was blowing directly from the
rig toward me. I remarked on how peaceful my bees were when I got home but
I did not make the connection with the H2S. The concentration was
extremely low, so the effect must be quite powerful.
