Input: Consider Input: Passage: The Bedrock Community Players is mounting A Christmas Carol, and all of the town's citizens are either planning to attend or be involved in the production: Barney Rubble is playing Bob Cragit, with Betty as Mrs. Cragit and his son Bamm-Bamm as Tiny Tim; Mr. Slate is Jacob Marbley; Wilma Flintstone is serving as the stage manager, while her daughter Pebbles plays Martha Cragit; even Dino has a role, playing the Cragit's family pet. It is Fred, though, who has landed the leading role of Ebonezer Scrooge. Unfortunately, he has let his role go to his head, thinking himself a star and spending all of his time rehearsing his lines rather than focusing on his job or family. On Christmas Eve, in his rush to get to work, Fred forgets that he must take Pebbles to "cave care", and later to pick her up from cave care. When Fred arrives at the theater, he discovers a furious Wilma, who breaks down in tears as she tells Fred about his mistake.

Input: Consider Input: Passage: The first inter-state numbering for the Roosevelt Highway was in New England, where the New England road marking system was established in 1922. Route 18 followed the auto trail from Portland northwest to Montpelier, where it continued to Burlington via Route 14. Many of the states along the route also assigned numbers to the highway; for instance, New York labeled their portion Route 3 in 1924. The Joint Board on Interstate Highways distributed its preliminary plan in 1925, in which a long section of the highway was labeled US2, from St. Ignace, Michigan west to Bonners Ferry, Idaho. East of St. Ignace, instead of crossing to the Lower Peninsula like the Roosevelt Highway, the proposed Route 2 traveled north to the international border at Sault Ste. Marie. It reappeared at Rouses Point, New York, following Route 30 and then rejoining the auto trail between Burlington and Montpelier. US2 and the Roosevelt Highway both connected Montpelier to St. Johnsbury, but the latter took a direct path along Route 18, while the former was assigned to Route 25 to Wells River, where it overlapped proposed US5 north to St. Johnsbury. There, where the Roosevelt Highway turned southeast to Portland, Route 2 continued east along Route 15 to Bangor and Route 1 to Calais, then heading north on Route 24 to end in Houlton.
