Actually, it's not just researching a novel. Looking for stuff to feed this blog (ie stuff that'll make interesting posts) I've stumbled over some fantastic sites.
Obviously Tumblr remains my favourite find-a-smile place. I love the images people share. Talk about travelling the world--and all without jetlag.
Other great sites are listed in the right sidebar.
But this garden and landscape design blog deserves a post all to itself. Fascinating. Thank goodness I decided to write a gardening hero and research led me here.
