I used to train for a hiking trip in a subdivision that was just being built. I was hiking up and down the same hill (massively steep) for hours wearing a generic baseball cap. Got cat-calls, stares, and whistles every single lap. Very next day went out again wearing an FBI cap. Not a peep. For what it's worth, the residents in the neighborhood ignored me when I was 'generic', but when I was wearing the cap (since it worked, I wore it many more times!) many of the neighbors stopped to ask what I was doing, what I was training for.
