They usually blow away here, too, but this past season they had 6" of snow on them before the fall winds came. After it melted off my neighbor was out there in a borrowed mulcher/vaccum attachment on a lawn tractor. I went to TSC and picked up one of those rear bagger leaf rakes 30 bucks off cuz it was out of season. I didn't want to invest a lot because I'm hoping this isn't a yearly occurrance, but I had fun collecting them
So much fun, that I was already thinking of a way to hook up some pulleys and use the winch to flip the bag. Those wet leaves were heavy. I had to get off to muscle up the bag and dump them.
