Have you ever fallen down a drain and landed in a criminals' secret underground hideout?

@smiler2012 It hasn't actually happened to me, but there is rumoured to be a maze of secret tunnels underneath the streets of my city, so who knows what's down there?

@BijouPleasurette do you live in London ? there are miles of tunnels throughout london wirh some suprising secret access points

@daddybloke No, I live in Manchester. I thought most of the tunnels in London would be filled with the underground railways. Lol :)

@BijouPleasurette no all still there , there are even spare unused lines for the underground ,tunnels that cpme out in westminster, bucks palace etc
