Mexico and regretful life choices

So, I'd been in Vancouver for 6 months, Canada for nearly a year. Vancouver was getting ridiculously expensive. I could have hopped over to Montreal for another 1.5 months, which in one sense would have been prudent -- summer in the north, yes? But I ended up going to Mexico City: cheap, not too hot (altitude), practice my Spanish, still American time zones for work. Drawbacks: air pollution, can't trust the tap water.
