Huge boomerang shape, bright lights, flying very low, treetop level, moving very slow, changed directions, disappeared n reappeared multiple times... would hover at times,, was driving and it would just disappear and reappear right next to me. I was on a back counrty road. 20 mins I observed this craft, called my son told him to go look outside, he saw it too.. I was about 4 miles from home at that point. My son and I witnessed just staying in same spot , disappear, and then reappear... for an additional 15-20 mins.. he got creeped out, wanted us to go in..
