I had finished mowing and trimming and I was behind a house doing the strip of grass between the street and the sidewalk. This strip was completely covered with a thick layer of mulched magnolia leaves and I was blowing them across the sidewalk and dispersing them into the yard. I got all the way to the end and had a nice large pile going as I turned and swept the whole pile with my blower jet I noticed something on the other side of the leaf cloud...it was a little girl on a bicycle...covered head to toe and pissed as hell. I immediately apologized and actually idle blew her off real quick which to my surprise she appreciated. Still mad as hell though. She had apparently rode directly behind me the whole time I was blowing the mulched leaves "stupid I think" but it was my mistake for not looking. At least I was not blowing more harmful debris...thank god!
