Well, Metro has annouced their final count. Their estimate is that the rail system carried 1,200,000 trips on Jan 20, 2009. This is of course the highest ridership day in Metro's history--and the only time rail ridership has broken 7-digits.
The number is called an estimate because due to station crowding, some station managers let people into or out of the system without paying. As this is the official number, the winner of the Track Twenty-Nine contest will be determined based on 1,200,000 trips.
And the winner is...
Tom Veil with a difference of 37,622.
Tom's guess was 1,157,622.
Our runners up are:
2nd Place: kenf, with 1,157,623 (diff: 37,623)
3rd Place: IMGoph: with 1,193,000 (diff: 73,000)
As for the average of the guesses, when averaging all of the guesses together, we get 1,308,558. That's a difference of 188,558.
Thanks to everyone for playing.
