Not that it affects me as I've taken my daughter this season and now sit in the family corner of the K&C (and will continue to do so unless I go alone) but having the away fans in the Kingsland North would keep them off camera a lot of the time! However I think logistically having them closest to the entry/exit bridge north of the stadium could present problems logistically. My guess based on nothing but making it as logistically sensible in my head as I can is that, if the club actually do this, the away fans will go in the Itchin North. All just a guess.
As for safe standing, I went to Elm Park back in 96 for the Reading vs Saints game that we lost 3-1, and my mate and I were able to jostle to the front of what was a packed standing stand (I was in with the Royals for my sins with my bomber jacket completely done up to hide my shirt) and I saw nothing wrong with it then.
