2005 broad daylight moving over Rt.41 in the Wadsworth/Gurnee, IL. area slowly drifting towards Great Lakes Naval Base.

We followed it for a long as we could but it seemed to start to speed up when it started heading towards Lake Michigan and we lost sight of it.

No sound. No lights

Black triangle about the size of a baseball field (home plate to outfield walls) and about one story tall.

Broad daylight, very low altitude, and it seemed like no one else noticed it but me and my daughter.
