I think if NM is sound financially in terms of the capital to build you wouldn't get many WT fans who would be angered by the WMDC helping Cas out with a funding shortfall. As long as it was repaid at a reasonable rate and time frame for all- one that wouldn't pinch the ratepayer, but also wouldn't squeeze the Cas as they settle into your new home.
That would ensure 2 new state of the art grounds with which to build a successful RL platform for the future.
IMO not many WT fans had any problem with WMDC being involved with J32 as long as we got the same assistance if needed. If NM gets the nod and is funded by YK (on the whole) I would have no complaints if WMDC came on board with J32 after FPP was given and made up the shortfall. All for the good of the game in our region.
