There is a boatyard in Fort Pierce that stores boats in various stages of decline and renovation. It's mostly wrecks, but this one has been almost completely restored.
I've been nosing around this place for a couple of years; early on, I asked someone if it was OK to take pictures and was assured it was. Today a self-appointed "watchman" followed me around, asked me for my business card and made me rather uncomfortable. I don't think I'll go back!
Hard to read that one- does he think you're collecting info for someone or maybe he thinks you might do boat portraits? I guess you should have asked why he wanted your card. Well, I'd be hesitant to go back as well- unless someone was with me. Good shot!
