I have been to the place in North Chelmsford once, and if I remember correctly it is down in a basement. When I first started bowling competitively in the early 1970s, I bowled at a 32 lane house in Seekonk. Almost all lanes were filled with leagues at 7:00 and 9:00 every night of the week. I bowled in a traveling league and we must have gone to 15 or 20 different places just in southeastern Massachusetts. Times have changed.
Don't remember any duckpin places in Maine, but I'm sure there were some at one time. There was even a place up in Burlington Vermont. For those who don't know what duckpins are, here is comparison of different bowling pins. Left to right: rubberband duckpin, duckpin, Canadian five pin, candlepin, tenpin.
