What's the story with the area around the pitch at Oriel? One side is the main stand obviously, and some other seating, much less deep. There is some room (8-10 metres?) behind the goal near the away end. The other end seems shallow enough, but just from the picture I googled now, there seems to be some kind of green area behind it.
The main limitation I suppose is the very shallow stand across from the main stand. But if the main stand was extended as far as it could go in both directions, or at least as far as say the 18-yard boxes, what would that do? Roughly double it in size?
