Saw a guy getting ready to board the train this morning. His bike had a sticker on it that said "People powered - no oil (wars) required."
What do you think they use to fill the tank of that locomotive at the front of the train you're about to board? Last I heard, CalTrain hasn't switched to biodiesel.
And even if he were so principled that he decided he would bike all the way to where he was going... Did they use canola oil to grease the chain on that bike?
You want to say that you're taking the train to cut down on our dependence on foreign oil, that's fine. Me? I take the train because I can sit here and blog or watch a movie or whatever instead of having to deal with traffic.
But it's ludicrous to self-righteously claim to be opting completely out of our petroleum-diven lifestyle. Even more so when you do it while boarding a train.
