I lived in Nottingham for while way back in early 1996 so know the place is really good for daygame as it has a quite large and busy city centre which also includes two malls and one large museum. By the way if enough people are interested in doing daygame there then why not make it a regular event and add it to the Saturday Sarge list here:
SS in your city | Saturday Sarge There are already regular Saturday Sarges in Manchester, Leeds, London and a few other cities across the world.
