A childhood belief about places

When my sister was in college (I was a great deal younger), she talked frequently of wanting to go to Nassau. I later learned that the place she meant was the capital of the Bahamas, a city I was then unfamiliar with. At the time, I thought she was saying "NASA", meaning she wished to visit the space flight center in Houston. Since she took far less interest in space flight than I did, I wondered why she seemed so keen on visiting the space flight center.
