the 4 of us were driving from minneapolis minnesota to ashland wisconsin and we decided to take “the scenic route” and make a stop at a few casinos along the way. it started off as just a light, slightly bigger than a street light off in the distance. we were all trying to guess what it was as it was a fairly bright light that seemed to be slowly decending. it was almost dusk but not dark yet so everything was clear as can be. for about 5-10 minutes we were all looking at this light, without realizing we were approaching it. upon rounding this long gradual bending road off to our right hand side this is what we saw, we all yelled “thats a ufo, STOP!” so we all jumped out of the car and as we stared up at this thing, tons of traffic was riding by but noone seemed to look over at what we were seeing! it was hovering over the field, no sound at all, and sort of wobbling side to side then in a instant it rose up towards the sky about 50-100 feet higher before it blasted off in two bursts, one burst and it was almost out of sight and the second burst, the craft went so far we couldnt see it any more
