Airspace Structure; Procedure
We saw a medium sized object perhaps 100-300 feet below us; we were at 4;500 feet MSL too small to be a plane. At first we thought balloons; but that didn't make sense with its track over the ground. It was headed into the wind fairly quickly. My student and I believed it was a drone of some type. There are no current [UAV] NOTAMS in the area we were operating. It was green; black; and silver in color. It had the appearance of a quad copter.
Flight instructor reported sighting a drone while on an instructional flight at 4500 feet.
