It's funny - for most of my professional life, I've had a long commute with no good transportation alternatives. I've been very in tune with gas prices for that reason.

Recently, I work from home mostly. I try to run errands by bike (but that has fallen by the wayside with the house selling stress of the last month, sadly). I drive a much more fuel efficient car. Even though I'm not biking, I'm still going ~3 weeks or so on a tank. I had hardly noticed prices were increasing until the news made a big deal of it, and my family called it to my attention.

I do hope people will look for alternatives. And that alternatives will be available. But, I worry that we're so far behind in infrastructure for alternative transportation (mass transit, bike, walk) that people will be forced to sacrifice healthy food for fuel.
