Make your list on 43 Things

I love making lists of all kind. Lists of places I have been to, lists of places I want to go to, lists of things I want to do, things I want to buy and so on. A site that caters to just this is 43things. I signed up with them last year and have enjoyed making my lists. For each item you add, you can specify if you want to go there/do it or have already been there/done it and also if you'd like to give advice to others on it. It's definitely a fun site that you can go back to again and again.
