I am very disappointed to hear of this date change. It now clashes with the very large and nearby Newbury radio rally
www.nadars.org.uk/rally.asp
This means that the attendance at RWB will inevitably be reduced as people choose which event they will attend.
I do appreciate the problems of choosing event dates, often well in advance, as I have been involved with this for the BATC but I do feel that this is a particularly unfortunate date clash.
For information the Newbury Rally tends to start early and is 24 miles away from RWBs so it would be possible to do a quick visit to Newbury and then attend the Auction.
