Walthamstow would indeed be a superb home for Speedway and also relatively easy (in London terms ) to get to. The problem with speedway returning there is not the nearby houses, but the GRA, or so I've been told.
I've heard from a learned source that there have been a few attempts to temp the GRA in allowing a shale track to be laid there, but each time they've met with the same answer - "Walthamstow is the Mecca of greyhound racing, and we (the GRA) don't want a speedway track ruining it".
Now surely the GRA aren't that flush with cash and any extra income would be welcome, so has anyone got any suggestions for laying a track which wouldn't detract from the "Mecca of dog racing"?
