large tringular object in the sky over my home

my husband and i were sitting on our front porch just talking. i happened to see a bright light off to the north east. i thought it was a plane at first, then watching it longer i thought it was a helicopter flying low over our creek. then i realized it wasn't making any noise. i alerted my husband and by then my daughter came home.  when the object looked like it came to a halt over the creek and slowly turned toward us it really got our attention. by now it started to move toward us and also ny now my daughter and i were shaking quite badly.  whatever it was came over the house and sort of hovered right over us. i ran in and got my son, he and my husband went out into the driveway to see it better.  what i saw was a very large triangular shape with three lights and a lot of smaller lights (?) on the bottom.  it gave off no noise except maybe a very low humming(?). also no illumination, but the lights were very bright. my husband saw a sort of purple swirlly light under  it.  i had gone in to call a neighbor but of course he didn't beleive me.  we watched after that for a few hours nad it seemed to make a grid pattern out in the field across the creek.  i called the oneida county airport and the tv station to see if anyone else reported any unusual lights in the skies over barneveld. no one did .  i watched it for a few hours after my husband went to bed.  about 2 years later there was a report in our local paper about anyone seeing ufo's to please draw and write about what we saw. i did and someone from mufon(?) came by to take our statements.  to this day whenever we're outside we are always looking.  we amy never see it again but what a experience we had . and i will always admit truth to this story. it's  something i'll never forget.
