What do you want to see before you die?

I was at the library yesterday looking for sources for a research project. Came away with something much more interesting :)
Fabulous book with pictures and descriptions of gardens all over the world. Would I be able to visit them all in my lifetime? Doubt it but so far I've visited 16 of the ones mentioned. Doesn't sound like many but there are some that are not included that I have visited.
So DH knows to start planning on "camera in hand" visits stateside and we will be compiling a list for our next visit to the UK :)
