I remember my first trip to Las Vegas, when I was 18.  It was between my Freshman and Sophomore years at college.  My parents had just announced that they were going to retire to Las Vegas and they wanted my brother and I to see what all the fuss was about.  We stayed at the Tropicana (back when it was still gold and only had one tower!).  The goal of the week was to show us around as much of the city as they could.  Since they were planning on moving here, you would have thought the emphasis was on the residential areas.  We saw that too, but as a first time visitor to Las Vegas, we spent most of the time doing what tourists do and saw about everything there was to see on the strip and downtown.
