I don't see many leather jackets worn these days around here period. But, will say that, when I do, it's by middle-aged men. I do have an old, (cheap), jacket I wear-I'm 66.
I hear you - I rarely see leather here and, yes, when I do it's likely to be old guys like us. Maybe we need an Under 40 and Wearing a Leather Jacket thread? That might be more unusual.
