For the past week there are millions of Monarchs all flying north. Every gust of wind blows them around but where ever they flitter they end up going north. They travel about 4 to 8 feet off the ground and I have no idea where they rest and if they are in groups or just end up going the same way. I'll have to google it. No matter how many birds eat them, or cars smash them, kids chase them, or they get blown away thousands find a way to where they are suppose to be. It is really an amazing act of nature.
