What does that mean!? Well, it’s tonight’s weather report and made me laugh, but it means the winds are changing! This weekend, Passport Diaries passed the 20,000 blog-views point in less than two years! Or actually, in just over a year, because I added the counter after about six months of blogging! Please help me celebrate by voting for your favorite blog header.

the fourth down is my favourite, but it's a tough call.
I love all of them! But the suitcase is still my favorite!
Suitcase. Only because nothing says "Passport" like a suitcase.
10 or 11th are my favorites, but I really like islands.
You have lots of good ones! I think you should continue to change them periodically. I realize I'm giving a cop-out answer by not choosing one, so here's the best I can do:
For springtime, #12 or #15 (the lovely blossoms against bright blue sky).
For summer, #9 (right before the 2 island ones).
For Fall/Winter, #1. It looks exciting.
The suitcase is good and all-purpose for your blog, but it's fun to display a little more variety.
Because you two really get around the trunk is most appropriate, but I really like the torii, too.
I like the Torii Gates… it's just so Japan. I love your blog!
