for one i would love to see the world.
yes, time available and expense are major limiting factors.
I also think that there is probably an element of fear among some Americans... perhaps there are some who feel as if their protection will not be taken as seriously abroad as it is here?
some people worry about kidnappings or murders abroad... Americans are not very popular these days with some nations, i guess some folks might be afraid they will be singled out and targeted?
i dont know - just adding it to the mix
