I don't wear hats or logos of any kind normally and I don't have any bumper stickers. I understand the point about not wanting to invite vandalism or theft but that's not really my motivation. I just don't like wearing or displaying a logo when I'm not getting paid to.
I don't make any secret about my hobbies and coworkers often seek my advice. In addition, I live in the country where my neighbors can't see me loading or unloading my car. They can hear me shooting though and I can hear them.
The hills around me can sound like a reenactment on any given Sun. afternoon.
