There is an urban legend concerning the outdoor set WBZ-4 built for "Boomtown" next to the station's studios during the show's "glory years" of the late 1950's and the 1960's. I don't know if it's true, but here it is:
The story goes that "Gunsmoke" star James Arness was in Boston sometime during the 1960's on some sort of business at a time when "Gunsmoke" topped the prime-time ratings. Arness and his driver were going down Soldier's Field Road, past the WBZ studios, and saw the large outdoor Western Town set. Arness and his driver pulled in, were given a tour of the set, and Arness is said to have told his driver "How could a local weekend morning children's show in Boston have a bigger and more elaborate Western set than our show, which is the most popular program in prime-time??".
If anyone knows if this story is or isn't true, please let me know. Thanks.
