My husband and I attended Expo67 in May-June of that year. We drove from Edmonton to Toronto, along with my sister and her very young daughter, where we stayed with another sister for a couple of days, visiting with assorted family members and also my terminally-ill mother for the last time (she passed away in January 1968; my Dad was already gone). We then left my sister and niece in Toronto and drove to Montreal, where we stayed with very dear friends from our Air Force days. (still our oldest and dearest friends, now living in B.C.) We enjoyed Expo67 very much and have many pictures to remind us, should we pull out those old albums. We also had a book, which went with the downsizing after several moves since then.
I might add that the trip to Toronto was not uneventful; our car was rear-ended the night before we left and I suffered from whiplash all the way.
