Duncan,
I'd seen the poster for this up on the club noticeboard but hadn't really paid it too much attention, so thanks for flagging it up here. It certainly looks a great event and similar to the West Midlands one Sean mentions its great value at £50 per person per round on 3 very good courses (though only one can really be considered South Yorkshire!)
I'm afraid that 3 week days in a row make it tricky for me, but if you or any other GCAers get a team together and fancy a practice round at Hollinwell, let me know and I'll sort something out!
Cheers,
James
