Paul that's not the point that some milkweed grows in some ditch in Washtenaw County. I know that and I would never claim the total absence of milkweeds in my county. The point is that a whole lot less milkweed grows in Washtenaw County grows in farmer fields now that most farmers have switched to GMO crops than the relatively recent past. Furthermore I see no reason why this trend would not be replicated elsewhere in the summer range of the Monarch in the central United States. I think you know this but that fact does not fit your political and personal agenda
