1) Got a dirty for this - is it the bird at the top? Don't usually zap those (they have a right to be there :-d ) but if so no problemo..
2) Also level. The runway and peri fence are at an angle toward the viewer, so I used the lamp post (If one rotates to match the fence, the lampost looks wonky!). I think I should really have left a note for the screener.
Incidentally, there's a cluster of those lamposts over the railyard to the left of the frame, and indeed some of them are not straight, however as threre is just the one in the picture, and it's close the the edge of the frame, I thought its better it isn't crooked!
