UFO with Lights in Bay View Location on Little Bay de Noc Shore line

I got off of work heading home down US2 & 41 from Escanaba, Mi.
I turned by the Grain and Grape towards my house.  I was at the top of a little hill, when I  noticed some colored lights: green, red, blue lights hovering on the shore (Clearing) of Little Bay de Noc.  (At the bottom of the hill it T-s, Right or Left)  If you went straight you would drive into the lake.
There is an old abandoned lumber mill to the right of what looks like a old boat launch.  We played there as kids and remember going into the water and feeling sawdust on our feet.
I saw the lights and thought, "why is there a  helicopter sitting on the shore"??  I continued driving down the hill and shutting of the music and rolling my passenger window down simultaneously. I was listening for the helicopter, but DID NOT  hear any noise at all.
 I stopped completely (after making the left hand turn) right in front of it.  The lake is appx. 150 feet away.
The lights either went out or the vehicle took off.  Not sure which.  All I know is I was scared to death.
I took off in a panic, pulled in my driveway and had to untie my dog (dobie) from his chain/doghouse which was right near the top of a hill that lead to the lake.  The dog is normally jumping and excited to see me.  I unlatched his chain from his collar and he made a bee-line toward the front door of the house with me on his tail.  I have never seen that dog act in this manner, Ever!!   I got inside and told my family about the incident and of course they thought I was crazy.  To this day when I go home, I am scared to death over that incident.
I have seen all kinds of strange things on that lake.   My family has seen strange things on that lake and in the woods as well.
Ask 10 Yoopers if they have ever seen something weird around the U.P. and 8 out of 10 will say YES!
