In '62 when I was 12, Elvis was in the Crystal River area filming "Follow that Dream". My dad was a big Elvis fan and they had advertised that he was making a personal appearance at Weeki Wachee Springs (home of the Mermaid Show) that Saturday.
We drove 60 miles up Hwy 19 from St. Petersburg to Spring Hill and when were arrived about noon in front of the springs, they had cones blocking the entrances and signs saying the lot was full, do not enter. That was the closest we got to seeing him.
