Strange noise at my house

[flash]

I got home from work Monday and kept hearing a helicopter hovering nearby with a weird sound .This thing was hovering for hours and hours driving me nuts so I decided to go find it and see what the heck it was doing. Georgia Power has hired this outfit to clear their right of way with a helicopter with a strange cutting attachment hanging below it ,crazy way of doing things but it seems to work good. Ya'll ever seen anything like what I have described ? I sure will be glad when they are done as my peaceful evenings at home are no longer peaceful.
