I bike along the I&M canal path, southwest of CHicago. I was once dive bombed twice after I had zipped past a family that had already safely exited the path for the water just before I passed. Momma was just one angry bird!! Have been chased down the trail this year. 6' wing span filling the rear view mirror is intimidating. Today encountered the same two geese and their 9 not yet flying progeny, just spread all over the trail and grazing in the grass at the side. Made all the noise I could but they just went about their business. After a ten minute wait while they waddled a few feet down the path, someone coming from the other direction, who also stopped, apparently convinced them to exit far enough for me to get by. This time only got hissed at. But seeing that they can cause mayhem and not really wanting to risk a fall (the last one resulted in a new hip), I guess I'll just wait them out.
