Driving along in my semi on a regular grain haul. my wife was with me. we both at the same time seen these two ufoâ€™s that appeared to be grid searching the whole area at writing on stone park. we watched from a stopped position on the highway. the ufoâ€™s flew about for 15 minutes then stopped side be side in the air. they flew into the valley together and were gone. we stayed 10 more minutes but seen nothing. never thought to take pictures we were so focused on them.
