I had something kind of interesting and concerning happen to me today. My wife and I went shopping at the closest small town in our area. We live in the boonies on a gravel road off a little traveled county highway. On our way home we saw 2 grey vans parked on the side of the road with a man in a hazmat type suit standing next to it. In one of the fields nearby there were 5 men dressed the same wearing respirators with sprayers on their back walking side by side going over the field spraying the ground cover. I slowed down and asked the man by the road what was going on and he replied nothing to be concerned about and to keep moving. I did. This was about 4 miles from my property and it does concern me. Has anyone seen anything like this? Any ideas or thoughts?
