People in attendance at the PGA Tour event today in the D.C. area: 37,613, per a local sports channel.
People in attendance at Al Gore's Live Earth event in D.C. today... Well, somewhat less than that. Guessing whether it was 100 times less, or merely 50 times less, that's just part of the fun.
Here's what look like empty seats at the marquee event in New York.
And drastically fewer people showed up than anticipated in Rio.
UPDATE: And, rather than attend a Live Earth house party, 140,000 in Florida showed up for an event that's not going carbon neutral anytime soon, no matter what Al Gore III tries to pull.
