"You have arrived"...I don't think so!!

So we had to drive from Saint Petersburg, FL to Savannah, GA today...Al Henderson Boulevard to be exact. Our calendar said it was Al Henderson Avenue, so Steven punched it into the GPS, which only brought up Henderson Avenue in Savannah. So he figured that was it and went with it. We were looking for a big church. One of the worst feelings has got to be when the GPS says, "You have arrived" and what you are looking for is nowhere in sight! We had arrived alright, just not where we wanted to. A quick call to the church confirmed that there is indeed a difference between Henderson Avenue and Al Henderson Boulevard. We were 13 miles out of the way (which is a long way when you've been driving all day). To top it all off, that 13 miles took 45 minutes because we were now in rush hour traffic! I think there needs to be a law that says no town can have 2 roads with remotely the same name. Second, come on GPS!!
