's list made me realize that I need to travel more of the US (I think I got 55), but this is the one I REALLY want to work on. 31/100, and there are some definite bucket list items on here.
How many have you seen, and what was your fav? What is your #1 "must see"?
M fav was probably the Grand Canal in Venice.
Next "must see" is either ruins of Athens or Pompeii. http://www.listchallenges.com/100-places-to-visit
