What would it cost to have a free game for everyone? Perhaps target one of the Cumbrian games and just open the gates (after bombarding the local are with leaflets and handouts at Tesco's and local press etc)
A nice sunny afternoon, bouncy castle for the kids. The extra food and beer sales would ofset some of the loss. I appreciate the season ticket holders wouldn't be happy but they would be helping their club. You could also have a donation gate where you can pay what you want to help .
I reckon on a poor crowd vs a cumbrian team we would get 600. knock off 250 season ticket holders that's 350. If they are a mix of consessions & adults that's around £4000K
Why not start a fund to raise money for a free open day and see what happens?
Good idea PM, although I think £4M is just a bit more than a couple of year's turnover.
What's to lose by giving it a go?
