huge, triangular craft, silent sighting in Modesto (Highway Village Area)

Me, My husband,Father in law, and 12yr old son were sitting outside our home looking at our zodiac signs in the sky, when all a sudden we spotted a huge light that came towards us at first we thought it might have been a drone until it came right over us and it was a triangle craft with three lights in each corner one light was solid red while the other 2 were whitish-yellow.  It made no sound at all and it was about 60ft wide huge craft.  It moved side to side, up and down, hovering over the 99 highway then would circle around our neighborhood again our neighbors also were watching.  We followed the craft on foot and in our vehicle.  After it got to the salida area it shot out of sight so fast we were in shock.  I posted videos of it on youtube if interested called modesto ca ufo sighting under melissa&jonathan helton.
