Saw my first sun dog in 2003.
The same day as the 911 attack happened I went for a walk to get away from the news. It was the first time I noticed chemtrails. The contrails that I saw in previous years would vanish quickly.
Didn't know about super moons until 2011.
These days it seems to stay daylight longer than when I was a kid.
The sun seems to give sunburn more rapidly these days as well.
