Thought I'd post here since there's more traffic.Was on a back road yesterday on my n1k getting a better handle on my right turn in curves (I'm a lot better in left turns)and was doing about 70mph.I've seen things in the back of pickup/work trucks blow out of the bed that you would think wouldn't have.Especilly trucks with pipe racks where the workers put things on there and forget to tie them down because they're in a hurry to leave the job site.Came around the curve and met two work trucks.First gave me a wave and the second,well,about that time something flew out on the road in front of me.Looked like a piece of paper wrapping but was trying to dodge it because I wasn't sure what it was and it was going all over the road.It was a six ft fiberglass ladder that came from either out the back or off the pipe rack.Never did flip up where I could see exactly what it was till I got right on top of it.It was coming at me and kinda going to the side but spinning around in the road and all this happened within seconds and I barely missed it by a foot,it that.Wind was blowing hard so may have taken it a little back to the center so it was really hard to judge where it was going and where I should go to avoid it.All this just to say that besides watching other drivers,you need to watch trucks hauling...anything just in case something flies out onto the road.I had very little time to figure out my "plan of action".The thought of something flying out like that just never crossed my mind until that close call.
