Sign of the times?

I was walking down street to get my lunch yesterday. It was probably about 33° out and I was noticing I was having trouble breathing (something I’d probably attribute to the humidity, since air quality [actually wasn’t all that bad](http://www.airqualityontario.com/reports/aqisearch.cfm?StationID=26060&this_date=02-Aug-07&startmonth=24hour)).

When I got to the Tim Horton’s, a cyclist rounded the corner behind me. I happened to notice that he was wearing a gas mask.

A real, honest-to-god gas mask. I didn’t get a chance to ask him if he really needed that thing or he was just making a statement. Then again, I certainly didn’t want to be out biking in that soup.
