Link to Sacramento 

I placed a wikipedia-link in this article where the word "Sacramento" appears.  Another editor, who appears to be stalking me and is reverting everything that I do, claims that I am "overlinking" by doing this.  I have read the policy, and think I understand it, and I disagree with him.  The word "Sacramento" was not linked anywhere else in this article before I made the link, and I think that my link provided good context for a reader who did not know Walnut Creek but thought that maybe they knew Sacramento.  Was there anything wrong with my link?  I would like someone objective to give their opinions. 74.234.45.208
