I thought it would be interesing to see what lists other GTD users keep in their GTD systems, and maybe I'd get some good ideas.

Here's my list 'o lists:
  • Activities to Do - places to visit, sites to see, local activites, etc.
    Beers to Try
    Books to Buy
    Books to Read Next
    CDs to Buy
    DVDs to Buy
    Gift Ideas for Deb (my wife) - whenever she mentions something or I see something she might like.
    Gift Ideas for Me - when I see something I might like
    Local Restaurants to Try
    Movies to See
    Office Supplies Needed
    Recipes to Try - whenever I find a recipe in a book, magazine, on TV, etc.
