I have to say that Sadie was a wonderful traveler. We we're really nervous about that because sometimes she can make a simple 5 minute trip into town stressful.
The other thing that made our trip smooth was our Garmin. I don't know how we ever traveled without one! In a strange city and want to know where the nearest Chinese restaurant is? Just type it in and the Garmin will direct you there. If you miss a turn it will simply say "recalculating" and get you back on course. No arguments, no getting lost.
