I have about 30 stinkpipes mapped, which is almost insignificant. There are 158 in Lambeth alone, apparently. So I realise it's time to get out there and start searching. The best way to do this is on a bike, and so I'll be slipping on the lycra and peddling off around Bromley & Bexley this Sunday, hoping to find undiscovered gems.
Lambeth will have to wait for another day unfortunately.
I still have loads in the archive to map, but it might genuinely be quicker to start from fresh - I have an idea where there are many to be found, eg, around shooters hill to Plumstead there's a little cluster of them, still unmapped.
People do look at me a bit funny while I'm photographing the stinkpipes, but I try to look all municipal and official as if I might be a surveyor - it's the look I adopt at work and it usually works.
