Short story.

Doing a pump test on a domestic well in the back country (everyone owns 20 acres or more). Most places don't have fences on the property boundary and the place just to the east of us has a boundary basically marked by a gully. My buddy Dan is with me helping me monitor some of the wells for interaction, but after it is set up with transducers it is all done by computer. The three geese next door are watching us curiously and Dan sees them and comments. The geese and I know each other well AND they still try to bite me. I tell Dan to leave the birds alone but NO. Flip-flops and all Dan heads into the gully and the geese immediately start craining their necks to follow where Dan is going while making some racket. As soon as he is at the bottom, they are waddling over ASAP honking up a storm. Dan's back in two minutes telling me how mean the geese are...tell me about it . I monitor that families well on a regular basis and while I measure water level in the well I am simultaneously smacking the geese with my clipboard to keep from being bit. Gotta love em.
