Today's Challenge is like that.  It's a very straight-forward question that might not have the simplest answer.  It's up to you to figure this out!

When you find the answer BE SURE to tell us what you did to find it AND why you believe this is the oldest city in the Americas.  

There's an interesting reason I'm posing the Challenge in this way.  I hope you'll also find out why I'm bothering to ask what seems to be so simple, and so obvious.
