Direction Challenged

Last week I got a distress call from my sister and niece, who were trying to find an alternate route home from a sporting event about 40 miles south of where I live (that's at least 150 miles south of where they live).  This isn't an area I frequent, but I've been there more than they have, so I did my best to help.

First I needed to pinpoint their current location.   "Did you cross the bridge yet, into New Jersey?"

"Yes, we just crossed a big bridge." my niece replied.  She was navigating while my sister drove.

"OK, tell me what the signs say and I'll tell you which road to take."

"Exit here is for Columbus Boulevard..."  

"You're at Columbus?  Then you haven't crossed the bridge."

"Oh yes we DID cross a bridge,"  my niece retorted.   "It was blue."  

"OK, well you're still in Philadelphia," I said, and proceeded to direct them to familiar territory from that spot.

Here's the bridge in question.  This photo was taken in the middle of the repainting process; the Girard Point Bridge is, indeed, blue now.  But it definitely does NOT cross the Delaware into New Jersey.
