People are scared of bikers. Not that I'd approach one who has a beer in one hand and is swinging a steel chain in the other but the ones I've met have always been interesting and friendly. Treat then with respect and you get the same. And who's going to feel aggressive towards a balding 61 year old guy with glasses and arthritic hands? (See illustration from a press photographer who got me from behind at the Chuck Berry statue dedication here.)
There is a detail in the top photo I really like. I was shooting in a very tight space and had to use a short focal length. That makes his hand and cigar disproportionately big and powerful. I wish the white foam cup was out of the frame, though.
