In 1985?

I think that was the year. We lived in Columbia Falls, Montana when I was about 11 years old at the time. My brother and I were walking down the dirt road at night. The place we lived in was a couple miles from the bottom of Tea Kettle Mountain in the valley. There were only a few people or families in the neighborhood of this country town. My parents had no problem that we would walk the road at night or play outside in the wee hours.
I remember looking up at the sky and remarking how many stars were out to my brother. I was about to turn my head back down when I saw a "star" move in a way that resembled a "check mark" and disappeared. I thought that was strange, but will never forget it.
Note: my first ever sighting.
