A long way to go...
If we are going to give a terrace option in this league make the away end open terrace Bury Road end. Home fans enter Sieve via Bury Road and from behind TBS. (They have let out away fans this way on occasion via tea bar) .Give little stand in corner for away fans who want to sit.
Can't see safety or police allowing the away fans to be split between areas of the ground in this way. Think you'd have to give them seats in the corner of the Carling if they're standing on bury road, but as we only have one turnstile into the Carling this wouldn't work either as you can't do hard segregation when needed. Don't see any solution with the current ground configuration which explains why it's done the way it is now. Just need better or more stewarding.
