My uncle was a truck driver. Most people don't realize it, but it's a pretty tough life.
I would think it would be neat because you get to see the entire country.
That part would be cool. The worst part would be the long days. Even with the regular breaks they have to take, they spend most of the time driving.t 
I guess that is true.  I know my legs cramp up after just a couple of hours of driving.
Same with me. But we kind of need them to transport everything over land: food and materials and other products. 
Yes we do.  I live in a river city, so we have lots of barges, but the large crates have to be shipped from the river to the vendors.
That's cool. I live at an ocean port, so it's the same kind of idea. I constantly see the trucks leaving for stores and manufacturing plants.
