#On the other hand, linking years of actual encyclopedic events to "1949 in NASCAR" or "1950 in motor racing" 
gives us a tool for eventually building those year-in-topic articles
 automatically builds those categories. Where some don't exist yet (like 1949 in both NASCAR and motor racing), are we better off adding the desired link and letting it be redlinked until the article is created, or just leaving it unlinked or wikilinked to the general year article such as <url>?
