I did a quick drive through on April 8, 2017. Whitlash is very close to the Canadian border, about six miles from it. There are a few buildings here, not much. There are no stores. There is post office. A lot of rural Montana is like a lot of rural Alberta, empty. I noted what I found interesting. I liked the church.
Whitlash Port is the border crossing. It is Aden on the Canadian side. When you get there it is an American border office with a Canadian office on the other side and nothing else. Not a lot of border traffic here.
