Because the Portland air quality isn't bad enough (its some of the worst in country), you have to burn wood on your little patio for recreation. That's great. Thanks for the respiratory disease you imbeciles. I love how much you say you care for the environment and you want to make your patio a "certified backyard habitat" while you burn wood and cook animal flesh and just get fatter and fatter and fatter. You are the perfect picture of American hypocrisy.
