I was leaving my neighborhood just after dark, as soon as i got to the main road i stopped at the stop sign and a bright object appeared right in front of my car about the size of a basketball. at first i thought it was someone shining a spot light at me from the field across the road, this lasted about 10 seconds before it vanished. i made my turn and started to feel strange about it. it then dawned on me that if it had been a spot light, the interior of my vehicle would have been illuminated, and it was not. it was an orb about the size of a basketball and bright blueish/white in color.
