Gustix.As far as I know Chris Mills and Chris Schramm are the only named riders so far.As far as I am concerned do not see why there has to be ANY reason for this fixture.Yes there was spare date,I think Kent supporters are grateful for regular Speedway (just ask Lakeside fans about fixture list being all over the place),Roger Cearns would quite naturally want to keep the Wimbledon name in the public domain (like when we had the Kent Laurels),it gives the riders of Kent another fixture and the riders that ride for the Dons.I suspect it is not easy getting a team together to represent the Dons (whether they have rode for them or not) and be competitive.
