So...

...this picture is horrible I know, but I was at Mickey's last week to grab a bite to eat and have a couple beers and parked outside was a beautiful knuckle. I talked to the guy and he said it was a '39. I've never seen one in Madison, so I was pretty stoked on it...I know, you can't see shit, but I took the pic with my phone and it just didn't turn out well.

Went to the Harley museum last fall before I took off to Georgia for a couple months for school. Took this short video of the wall of motors and the cool interactive video screens they had.
