Busy street, busy times, people out on the streets, mixing together : well, we can dream can't we! This week our Sepia Saturday Archive A-Z has reached the letter S and we are calling in on the archives of the Salt Research Institute. You can take from the prompt what you will - there are enough potential themes there to keep everyone busy. All you need to do is to choose you theme, choose your photo, post your post, and add a link to the list below on or around Saturday 14th August. And look who has been busy - here are the rest of the prompts in this Sepia Saturday sequence. After we get to the letter Z what happens - wait and see ... it's time for some changes.
