It was a chilly commute to work this morning. Another 60 miles on the bike in freezing temperatures. If you ever wonder about the polluting effect of cars, ride a motorcycle on a major motorway/interstate when it’s 32F outside then exit onto a smaller road that is hardly used. Even if you stay in full sunlight, you’ll notice how much cooler it gets. That’s because there aren’t hundreds of cars’ exhaust fumes warming the air.
