There are tunnels everywhere though....that have been there for years.

In the town I work there is a church and there are tunnels under the church to a pub across the road as that used to be where the vicarage was and the vicar used the tunnel in times of inclement weather. They are now blocked off but I bet my house if they were opened up there would be a myriad of things in there that have been discarded and people can't be bothered to dispose of properly.
