Current thinking is to go to the Crick show next year which is the Late May bank holiday 23-26th May 2025. This will take a full 12 days from Burghfield so probably leave around 10-11th May.
From Crick the thinking was to head down to Norton Junction and meet up with Maisie Grey again, then down to Gayton and the Nothampton branch to join the River Nene in Northhampton. Spend some time exploring the Nene and possibly Middle levels and the Ouse and or Cam before returning to Burghfield, possibly via London.
Details of route, duration and dates still to be determined
