Quite agree. For all the stick we give Oxford about having a three sided ground, we have effectively had the same for a long time now. The Stratton Bank is where I first stood when I started coming to football and where I had my season ticket during the Premier League season. When the Bank was packed, the feel of the ground changed. It must be 15 years or so since it's been used week in, week out.
If we are going down the piecemeal redevelopment route, it's clearly the two ends that need sorting first. Not ideal, but if we can do a decent job at both ends the feel of the ground will change for the better...no doubt about it.
I'm young enough that I don't remember the Stratton Bank being used to any great extent. I think the only two instances of it being full that I remember are the Reading Friendly before the 2010/11 season, the Wigan cup match the same season, and when they had that Excalibur sponsorship drive thing towards the tail end of last season. I don't get along as much as I'd like to mind, so I could have missed some (but I doubt it).
Sticking a roof on it is a very sound idea for all sorts of reasons. It frees up the Arkells/North Stand for home fans, means there's not as much as a problem with security for that reason (not saying that there was in the first place...), gives the board room to expand in terms of average attendance, and makes the place look a bit more high-end. It'll improve the atmosphere no end as well, with the noise being bounced off the roof and back towards the spectators just like in the town end. £150,000 does sound a little cheap mind. I'd rather they overestimated the cost. Then again, perhaps they've had the surveyors in already with a quote, or Jed's going to stick a conservatory up.
I personally think there's nothing wrong with piecemeal improvements. Surely it's more financially sound taking small steps you can afford by yourself than big ones where you may have to get other parties involved- we've all seen what's happened to Coventry with regards to that. If JedCo go around the ground, improving on what we've already got, putting in better facilities (*cough new Town End, cough*) and keeping the place up to date, then we'll retain the history of the ground and our financial security. Okay, we may not have a brand-spanking new, state of the art bowl of a ground with a cinema next to it and four casinos built in, but we'll have a modernised CG, and I do think a lot of fans would prefer that.
Perhaps they could put the concert stage up a bit higher and kill two birds with one stone.
If they're fiddling about with the Stratton Bank anyway, and they want to have regular concerts, perhaps they could also do some work to have some kind of structure built in to facilitate a stage going up on the Stratton Bank itself? I'm no expert mind, but perhaps a 'base' for them to erect the stage off of quickly would be a sensible addition.
