Visited States/Countries Maps

So where along the way while I was surfing the web I came across this interesting website.  You click on the states/countries you've been to and it tells you what percentage you've been to.  I'm not sure why I find it so cool.  Maybe because I like to see how much I've traveled?  Here's my US map:
  


I've visited 38 states...that's 76% of the US.  Making 3 cross country drives in a year and a half helped a lot.  Doing the northern route for one, a middle route for another and a southern route for the last one really helped.  I'd like to visit all 50 states.  I wish I could pick just one as a favorite.  I have many that I want to visit again, like Wyoming and Alaska.  I really want to go to Colorado.  Not sure why, I just think it must be a beautiful state.  Maybe someday I'll learn to ski or snowboard and than I'll have a really good reason to visit! 

Here's my world map:



It's a lot less traveled.  Only 11 states or 4.88% of the world.  I think we need to get some world travel going on, don't you?!?!?

I think it would be cool if you checked out the maps and posted your own, but that's just me.  You don't have too.

Out of all the states you've visited, what's your favorite one?  Why?
