Yes? Or No?

Spotted in a little park. I wonder if it is a successful way of reminding dog owners to clean up after their pet.

My second afternoon volunteering at the Museum of Archaeology and Anthropology, locally known as Arch and Anth!

I "explained" lots of items to quite a lot of visitors as the gallery was busy. I really enjoyed myself and had some interesting conversations. My only problem was working out who maybe didn't speak English as there are lots of overseas visitors. I dont want to embarrass people, yet my job is to initiate most of the conversations. But all in all I felt very happy with my second afternoon at the Museum.
