I thought it was about time I updated the panoramic photo linked off the front page of the blog.
Here's the state of the layout as of today. Moving from left to right, the changes include: quad bikes parked by camera tower, first aid building, commentary building, wall clock in the shape of a wheel, more art on the walls, Spitfire flypast, lots more figures in the pit lane, cardboard control tower replaced by the vintage version originally on the left-hand side of the track, big screen, trees, more spectators, timekeepers' hut, additional camera tower, entrance hut with turnstiles.
