Thank you all.
I will buy a Y ticket.
I won't know if the trip is on until Friday 6 PM at the earliest.
If someone lives in Ottawa, we can do the exchange in person over the weekend.
Otherwise, we can work on overnight delivery for receipt in Ottawa by noon Monday provided you can accept my word as an FTer to return them immediately if the trip is off.
Either way, my e-mail is indeed
[email protected], and it works!
This is a wonderful community!
