I was driving east on hwy 68 just south east of cambria mn. my radio turned to complete static and i noticed an object in the sky at my 2 o'clock position. the craft appeared to be silver in color and elongated like a cigar, but flat on the top and bottom of it. it also appeared to be reflecting the afternoon sunlight quite brilliantly. i attempted to pull over and get a video of it as it moved in a slow manner towards the south. at this time i noticed a low frequency hum that felt as if it were resonating in my deaf ear. as soon as my car stopped on the side of the road, the object ascended very rapidly straight towards zenith in the sky. i lost visual of the craft after a couple seconds.
