metro rider (3)
March 29, 2004
every time i go down i take a transfer and every time i surface i take another transfer. this way i can calculate how long i have been riding: the time stamped on the “surfacing” transfer minus the time stamped on the “going down” transfer gives me the duration. i keep all the transfers and log all the details such as the date, the two letters stamped just before the time, the station i went down in, the time i went down, the station i surfaced in, the time i surfaced, and the duration of riding.
