I'm planning a trip to Europe this fall. My plan is to fly directly to the destination, and then connect through Canada on the way back. Since I'm in the Northeast, Amtrak could be an option out of Toronto or Montreal. (Bonus points for Amtrak's more liberal free baggage allowance)
I don't know if I'll need my laptop, but I have a DSLR that I don't want stolen or damaged. I might just route back through Canada in general regardless of an electronic ban to get around anti-American harassment from foreign security agencies.
