As I was in the San Francisco area, I took trains and such with my friend to get to San Francisco itself. For about a 30 mile trip, it was cheaper to pay the $2 train fare. We spent abou5 $5.50 on public transportation per person that day, which seemed like a lot of money, but in truth we saved. Now, if we had a group of 7 people to carpool, that would be another case, but with 2 people it was logical to take public transportation. Now, where I live, it doesn't work, but I somewhat would like to move back to that area when I'm older because of the money that could be saved. Think, save $10 a day on fuel and that's $3,650 in a year. Of course, there are many other factors to that, such as housing prices and other expenses, to be considered, but wouldn't it be nice?
