Will flu fears dampen the AIA show?

Other than O’Hare airport looking rather empty for a Wednesday, I have seen no signs of concern among travelers as I made my way to San Francisco for the AIA Show. OK, I may have given the guy in the seat in front of me a weird look as he coughed without covering his mouth. But no surgical masks, no panicky mobs or anything else unusual in beautiful San Francisco. However, it remains to be seen if the crowds in the aisles, and the number of booths, are similar to what I remember from Boston last year.—Melissa Larson
