My wife & I walk around our neighborhood almost every day, weather permitting. If we hit every street, it’s about 3.5 miles. In one yard just near the entrance, there are two trees close together. A vine is going up & around both the trunks, creating a dense amount of foliage. Walking by there the other day, I saw a Monarch butterfly going towards the trees. Then another. Then another. Looking over at the vines in the trees, there were dozens of Monarch butterflies in there. We’ve been able to observe them for three days straight. Today when we walked by, there were none. Obviously, they are migrating to Mexico. The blooms on the vine have likely become a feeding station for them. I’ve heard of the huge masses of Monarchs in some valleys in Mexico. This is about as close as we’ll get.
