Years ago my wife and I were looking for a new car. We were at a car lot in Hendersonville, NC, I went inside to talk to someone and when I came back out my wife said to look up. The sky was almost black with the Monarchs a few hundred feet above us. The migration should be going over us about now but I haven't noticed any.
I have a few small patches of milkweed growing around our property but I haven't seen any Monarchs on them. They have been past the flowering stage for a while now.
