Candles pins are like sticks. Duck pins are like ten pins, but a third of the size. Also duck pins don't have the rubber bands that go around candle pins (knowing that not all candle pins have those).
But it is similar in that most of the lanes that have them have been around forever, the equipment is old and no one outside of one part of the east coast has ever heard of them.
I'm sitting here listening to my boy and his friend play X-Box and do boy stuff - like fart and make jokes about farting. High culture we have going on here let me tell ya.
