Walthamstow has got plenty going for it - "it has the requisite villagey middle-class bit, but with a proper gor-blimey guv'nor East End heart" says one newspaper article and Mark finds a town mid-gentrification. The dog track has gone, the famously long market remains but there is also a Viking Shop and an extraordinary showroom and workshop with a vast range of neon light fittings called God's Own Junkyard. There is a museum dedicated to the designer William Morris who used to live there and there's evidence of a recent war too in the form of the cycling scheme known as "mini-Holland." Hopefully Mark will tread carefully. With guest local MP Stella Creasy.
