Gas where I live is $1.34/litre ($5.07/gallon for those of you in the US). It's sick! I sold my car last month and am bicycling to work and college. I love it actually. I live on a bus route too, so I can always hop on the bus to work or school if I wanted (I get a bus pass as part of my tuition fees).
