I've just been looking through my entry forms for this year, and on the back of BARC forms, there's a new box, labelled "Do you wish to make a donation to the 'Marshals Fund' ?" - never seen that before, so it must be new.
Bravo.
I'll try and donate at least a tenner for every round I enter, I reckon - and it still works out cheaper than the BRSCC
