When we were kids, we lived in a house with a front porch. Loved that porch. That porch was used for everything, from just sitting quietly on the swing, using it as a hiding place (it had solid sides up to the railing) having all the kids in the neighborhood just hanging out, sitting around, talking, laughing.
And once a year it was used as a meeting place for the invaders from the north. I don't know what their real name is, but we called them Canadian Soldiers. They would come by the hundreds and meet on our front porch. Covered that porch. We would come outside one day, and there they were. We could pick them up by their large wings and set them on our arms. They didn't bite and they didn't try to fly away, they would just sit there, tired after their long journey. And soon they would die. Don't know what their purpose was but they enjoyed our front porch for a few days just as we did.
Took this picture yesterday. These were the only ones that showed up on my back wall. Maybe more would have come if I had a front porch.
