Spending all day in an airport with a baby doesn't sound to me like it would rank terribly highly on the list of pleasurable travel experiences. I can't imagine it's even a particularly easy airport to go for a run from.
Is it still smoky in Vancouver?
Yup, it was a pretty long day. Tom and I traded off babysitting and trying to get work done. Made easier when we found a playground at the end, made worse when our flight was delayed an additional hour when we were about to board... but made it back. And yes definitely smoky in Vancouver. Not quite as bad, but also smoky in Portland.
