A chat not so long ago with Raddog about drains in and around the West Midlands lead me to sub-urban.com where he had mentioned Sirenity. After some research i gauged the rough location and seeing as the weather had been decent we set out out in search of it. Visited with Tunnel Lover and as time was a constraint on this trip it will require a return visit to see it all. I think this has given me the required motivation to actually start exploring what is directly under our feet more, so watch this space.
