There was a gigantic biker ride into Milwaukee, WI. to celebrate the Harley-Davidson 100th anniversary in 2003.
August 28-31, 2003. FWIW.
It might have been summer then.
But this pic is BS in the context of today.
It is freaking snowing outside right now!
Here’s the mystery picture here:
On Thursday, September 11, the nation will remember the attacks of 9/11, and as many as two million will be on motorcycles converging on Washington, D.C. in the 2 Million Bikers To DC Rally.
