Somebody write this joke for me

I know there's something there but I'm not sure exactly what to do with this.

Mayor Ray Nagin, Sen. David Vitter (R) and Rep. William Jefferson (D) were among the dignitaries who rode the first streetcar to run on the line.

For the time being, only the one-mile loop Downtown to Lee Circle has been restored, according to the RTA. The streetcars will not travel the six-mile historic line through Uptown for at least another year.

This was the first phase of an $11 million project to rewire the entire St. Charles line.

Something about... riding around in circles... or... a loopy set of passengers embarked upon the inaugural trip along the loop... I don't know.. help me out.
