Keep in mind that while it may seem petty to call it an error because the Slabber placed the word "The" in the title, in this case there is a recognized distinction as there are (were) actually a "The New Frontier" and a "New Frontier".

Its not as if the Slabber merely added an article to the name, he actually made it refer to a different listing.

I know Pam gets it, but for our new friend I didn't want him to think we are playing word games.
