| Having gone to CMU for four years and now attend school in LA, I can say that I feel Pittsburgh's air was much cleaner feeling than LA's. When I get off an airplane in LA, I can taste the air. It's not that good, clean, crisp taste you get in a rural area, it's a pretty gross pollution-y taste that's one of my least favorite things whenever I fly into here (the traffic on the 110 through downtown LA at all hours of the day being the least favorite).
Also, didn't Pittsburgh just rank in the Top 10 Greenest Cities in the World a year or two ago? |
