I found a black rolling suitcase near Mile Marker 85 on Highway 2 in Eastern Montana. It was slightly open, and it seemed to have been there for a while. I'm hoping to reunite this suitcase with its owner, as it appears to have some personal items inside. Please reach out to me with details if you think it might be yours!
