I'm not planning a trip any time soon, but I do find this luggage cover interesting (it's supposed to keep your bag cleaner, more secure and allow you to find it more easily). I'm wondering how practical it would be.
Oh, and I already posted a link to this on Twitter, so my apologies if you saw this, but I really liked it, so I'm adding the link here, too. If you click through, you'll see a panorama of Paris with Yves Montand singing "Sous le Ciel de Paris."
Enjoy your travels even if it's only armchair traveling with a good book!
