In a final two day burst of activity (including having to drive
out to Grantham to find the right capping stones for the top of the wall) the
tunnel is now pretty much finished - just the roof to go on, which will be of
timber construction with felt on top, probably removeable in case of
emergencies!
The boys and I have an appointment with a large pot of black paint
this weekend for the lining walls, then it's over to Mrs P for the landscaping
job outside.
