Saw both carloads of Sags on my way back down the M6 last night.
One of the 'cars' was a Reliant Robin with some deluded ***** waffling on about 'unlucky, da shit' or something.
Given that most of the shots and defensive clearances end up in Row Z, I suspect that they start with Row Z and work down. So they would get to about Row S before they ran out of space.
