could be a lot of fun. you talked about those experiences including also when you were in canada. you visited the old residence of a poet, robert service, who was very familiar to john mccain. >> yeah, that's right. of course, we took plenty of trips to war zones in iraq, afghanistan, a all kinds of other stands in other places as well. there was a trip, i believe, in 2006 when we went up to the yukon territory of canada. we landed on white house where nobody on our deligation had ever been before. the mayor of the town there said offhand that the canadian poet, robert service, had grown up nearby. of course, nobody in the delegation heard of robert service. mccain's eyes lit up. he got excited about this. we couldn't figure out why. he explained when he was in prison in hanoi, he spent two years in solitary confinement with time on his hands.
