In response to sighting of 08/15/78 in St. Albert

I believe I saw the same object in the about the same time, give or take a year.  But, being an estimate of time, and the grade and age I think I was, I think it's the same PLACE.  My experience took place in an area of St.Albert where the field is huge and borders with schools. Coming home in the evening from outside skating at one of the schools, my sister and I crossed the street and entered the field through "the hole in the fence".  As we walked about 15 ft, just by the ball diamonds, we noticed an extremly huge "spot" light crossing back and forth through the field, as if searching for something.  There was no sound, and nothing to see but the light.  We froze in one spot, and watched this light as it virtually "searched" the field from one side to the other.  As it approached us, being frightened, I believe now we were in shock, my sister pushed me down, and told me to lay still and quite as she covered me in snow.  She then covered herself next to me.  She was so quick to act. I think she had covered both of us in less than 30 seconds.  Just as she finised herself, the light passed our heads by inches.  As the brightness of the light passed, we peeked to see that it was once again on the other side of the field.  We jumped up and watched as the light disappeared straight up.  For a second the sky was dark, then a bright streak of white and red shot south through the sky.  I have NEVER seen anything move and dissapear so fast in my life!We ran back to the "hole in the fence", crossed the street, to where the street lights were, and took the "long way home" along the houses and street lights.  We were frost bit, and I don't have any memory of entering our home.  I have tried to speak to my sister about this incident many times through the years, but only lately, has she spoken about what happened in the field.  I don't even remember entering our crescent.
Witness indicates that date of incident is approximate.  PD
