Probably not fair because of my job.
Outside of work, most famous would probably be Ronald Reagan, in 1976 when he was running for President and lost to Gerald Ford.
Went to college with Jamie Leigh Curtis and Dean Butler (played Almanzo on Little House on the Prarie) Had a class with her, but didn't know here. Dean is a Fraternity Brother.
In the 80's DW and i cruised on NCL when their big deal was having celebrity entertainers on board. Met Norm Crosby, Jack Jones, Shields and Yarnell, and the 5th Dimension. They also had sports celebrities on board who were paid to mingle with the passengers. Some NFL player I had never heard of whose last name was Nixon and NBA Player Moses Malone.
Through work...Bob Hope, Dr. Joyce Brothers...Raymond Burr....Allison Arngrim, Shaq..Ruta Lee....Jay Leno........I can't remember all the folks who I have met through work.
