lots of smoke in Vancouver lately. There are a bunch of forest fires out in the mountains/interior of BC. The smoke usually doesnt drift west towards the coast, but it is doing that right now. As HardyW said, air quality of Beijing. It's kept a bunch of commuters off of the roads, but it hasnt bothered me much at all. I just take it a bit slower, but have still been riding every day. Apocalypse Now sunsets lately.
