There are 2 reasons:

1) No one on either side really wants to
2) It is too late to go down that line, apart from Newmarket. "finding a site" the way you say it sounds easy. It has taken years for both sides to even get to this point. What makes you think we could just magic some land and then the money to build on it?

From a Castleford perspective what RW should have done when he realised the problems faced with GH, was to get behind NM as joint tenants on a short term basis (1-5 years), whilst also persisting with selling WR and moving to GH. I'd have thought, that would have guarenteed both clubs SL spot whilst allowing him time to find a buyer.

Although it's easy for me to suggest that as a Wakefield fan

The problem with that approach, from a Cas perspective, is that he'd be perceived as having taken the first step towards merging with us; once we were in the same stadium, there would be massive pressure to do so from just about every quarter other than fans of the two clubs. That, coupled with the loss of revenue they'd suffer due to a) not owning their own ground and b) fans staying away in protest, would cripple them financially and add weight to the merger argument.

To the casual observer, a merger of WTW, CT and FR at NM Stadium makes perfect sense - to the thousands of people the success of that merger would depend on, it's unconscionable.

I guess that approach depends entirely upon how confident RW is in delivering GH in the near future. And i do agree, i can see why they wouldn't want to share at all, if the shoe was on the other foot i wouldn't want to share unless it was guarenteed to be a short term move

I don't think he's in any way confident about anything right now, including his own job; I know that some Cas fans will defend him (the 'he may be an idiot, but he's our idiot' approach) but he has all the hallmarks of a desperate man, clinging on for grim death whilst the house of cards he's created falls down around him.

I have some sympathy - what's happening over there is almost a mirror image of the death throes of Ted's reign at WTW; on balance, they deserve better and I hope they get it before it's too late.

The problem with a ground share (and before I'm shot down I know that the 2 Milan football clubs manage quite well), is that for many, it would be seen as a first step to a merger.
If there was an undertaking from the RFL that the "m" word was removed from their own agenda, then maybe this could be a possibility.
As long as the ground was in Wakefield

The Milan analogy annoys me. That is one example, there are hundreds more to counter it. Why don't Liverpool & Everton share? Man Utd & Man City, Arsenal & Tottenham? Villa & Birmingham? Real & Athletico Madrid? And many, many more. Mainly because they hate each other and want a seperate indentity. Forget sharing it will not work for either side.

They also represent the same city, which helps matters no end. Wakefield and Cas are two different places.

Hull FC and Hull KR! They have a fantastic stadium they could share - but they don't because it is not culturally acceptable!

But to the mass populous they are lumped in with Wakefield, sadly!!

Our identities as individual clubs is not as strong i would say as some of the examples given, it is up to us to push our clubs, a real marketing push should be given to the derby games, and hopefully if we are both filling our new stadia for derby games this will help develop the identities further.
A full house at WR or BV goes un-noticed by many, when compared to some other attendances in SL these days.

Exactly and that is why it will never happen. I for one would never watch a Wakefield side who played out of Glasshoughton and I doubt i'm the only one that thinks that way. And i'm sure many Cas fans feel the same about Newmarket. And as such it just isn't financially viable for either club and so there is where the argument ends.

The argument now is whether the people arguing against Newmarket happening and the people who will ultimately make the decision want the blood on their hands of professional sport in Wakefield.

Absolutely spot on - and the reason I argue for caution in terms of dismissing RW's intervention in the PI; this decision is absolutely massive not just for WTW, but for RL at all levels in the Wakefield District.

I aren't trolling - it's a serious question.

Is our hate for one another going to get us both thrown out of SL just because we can't agree on sharing a Stadium? Come another 2 years will it really matter? Because let's be honest, there's a very good chance niether of us are going to have a Stadium and will most probably get thrown out in favour of Northampton or/and some French club.
