I was driving my truck( an older 1978 chevy silverado blue and silver in color) west along highway 616 outside of leduc alberta i was on the east side of coal lake at the top of the hill, it was a clear day nice weather, i was happy and looking forward to seeing my son, picking up his mother. as i was heading west, a couple hundred yards before i reach the top of the hill directly in my line the site i noticed something odd floating a little bit south of the center line of the highway, at first i thought it was something attached to a power line or a wire, but as i got closer i saw there were no wires in the shape of it was like a medium sized safety deposit box and it was a medium gray too dark silver in color smooth surface it made no noise they were no lights and it seem to just float about 20 to 30 feet above the road. i pulled over my vehicle i got out i stood there for about 5 minutes directly under it staring up at it, it was really weird i think my brain went into shock and i didn't know what to do so i just drove away, went into edmonton picked up my son and his mother, drove back out to my place and this time both connie timpson and myself scene it's still sitting there we stopped again looked at it, at the time we did not have a camera or cell phone. it was doing the same thing just floating about 30 feet in the air wasn't making any sound no lights no markings just floating there. again i didn't know what to think i didn't know what to do we just got back in a truck and drove away. it is been on my mind and bothered me for a long time, if i ever mention to anyone they looked at me like i was crazy. i have searched the internet i have never found any other descriptions like what i had seen, and i did have a witness to the event good still not sure what to think but i thought i would let somebody know. thank you very much for the opportunity to express myself.
