This started a cascade of memories. My mother used to take me to the bowling alley where she bowled in a women's league. Sometimes after her game she'd play duckpins with me. When I mention it to most people, they seem never to have heard of this flavor of bowling.
Since Deford mentions that he grew up playing it in Baltimore, and I most likely played it in Maryland as well, growing up in Washington, D.C. as I did, I wondered if it was more of a regional thing. According to this site, "Duckpins is mostly bowled on the east coast, but due to a lack of media coverage, it's less seen than tenpins."
So there you go. Once more the Internet comes to my rescue to let me know I'm not insane "qbullet.smiley".
