I was just pricing a trip into Baltimore, seeing how much it would be if I drove the whole way versus if I drove to the Cromwell light rail station and took the train the rest of the way.

Mileage driving into Baltimore: 30.7, so round trip: 61.4. I get an average of 31 miles to the gallon, miles divided by mileage = 1.9806451612903225806451612903226 . . . or so. Times $2.75 (price per gallon), estimated cost of trip is $5.44. Well, actually $5.4467741935483870967741935483871, but who's counting?

Okay. So, with the same calculation, driving to and form the light rail station is estimated to cost $3.2467741935483870967741935483871 . . . and the round trip on the train would be $3.20, so the total cost of the trip is . . . $6.4467741935483870967741935483871. Exactly one dollar more than if I drove! To the, like, .0000000000000000000000000000000001 degree of similarity! What is that, a billionth of a billionth of a billionth? I'm not doing the math, I have to go catch the train.
