Well, of all the flights we took, and we took about 12 to-ing and fro-ing from everywhere, the flight from Vancouver to Toronto was the worst. We were delayed for 4 hours in the Vancouver airport, but told to wait in 15 minute increments so we didn't leave the airport. Because we are readers, at least we can hunker down and pass the time, but apparently we missed the free snacks and drinks because we didn't look up from our books. It was just juices thought, so we weren't that upset.
We met a woman on the flight who had been to NZ and Australia for about the same time as us. She was about 10 years older than we are and she had done walking tours of all the places we went. She did a 4 day hike around Milford Sound. She said the food in the huts was great most of the time, but the sleeping arrangement were not that great. She said most of the people were under 30, but she didn't have any trouble keeping up. She was telling us the Milford Sound hike was an option of her walking tour and only 4 people went on the hike, she did and some one closer to her age and one father and his son. You can never tell by looking at people! I often thought when we were on the trip, that some of the dive leaders may have had misgivings when Spud and I asked to go on dives, based on our appearance. But they never showed it, not be even a flicker of a face muscle! And unlike all the young people selling tickets at the attractions, they never asked us if we were seniors!
