585,281 people had ridden Metro as of 1pm today, which means we’ll probably eclipse the record some time around 7pm today, if my math is right. I would bet we’ll clear 1.3M people by the time that Metro closes tonight.
Update: The 4pm graphs are out for the Metro, and they’re up to 806,000 riders for the day. At 4pm. So, by now (5pm) it’s likely that record has been topped, and it’s probable that they’ll be well over 1.3M riders for the day.
