If you could just sit around a campfire with a cold beer and talk to anybody for 2-3 hours who would you choose. Lets not consider relatives who have passed away. We all would like another chance to talk to them folks.
1) Famous inventor / businessman. Somebody like Gates, Henry Ford, Edison ect.
2) Famous politician. President, Lincoln, Washington ect.
3) World famous person. Elvis, Mandela, famous actor, Winston Churchill.
For myself I would love to talk to somebody who started a world famous company and built it from the ground up. Where they got their money, how they hired, how they expanded ect.
Oh well, just a way to pass a rainy day.
