Other things of note

I don't want to lose these things:

• The Economist hosted an online debate about aviation security between security expert Bruce Schneier and TSA director Kip Hawley.
• The Atlantic explains why conservatives are afraid of cities.
• a la card Chicago, which sells a deck of 52 $10-off coupons to area restaurants, has a one-day promotion today for 50% off. (Enter code "SPRING2012" in the appropriate box.

That is all. More UK and France photos later today.
