I don't think it would be difficult to round up enough volunteers to get the job done in a few days, BUT, by the time they've all been to Salisbury or Bath to get their health & safety certificate, then got hard hats, hi viz jackets & safety boots, then got training & certification in the use of a broom & paint brush, then done a course on COSHH, then filled in a 20 page risk assesment, etc., etc., etc.,
Easiest solution is to pinch Debs' idea, leave it alone & call it the Bratton Grey Horse, then nobody will be disappointed.
