BB had 22 or 24 (not sure if the numbers on the tournament thread include the drop-outs or not), but remember that's an established event within an established tournament circuit.
I think we'd be lucky to get 10 non-club members in, given what I see posted about UW turnouts, and we might not have the pull of glass.
That's not to say we can't try, just want to put some realism in.
And selfishly, so that both Gary and I could attend we'd have to limit it to the 1-in-6 weekend we're both off.
