See, if I’m one of the instigators, I’ll feel like I have to show up.
I’m not sure enough of locations to suggest one. As far as dates, with the exception of the first and last weekends in October, I’m mostly available at least one day during the weekend.
And while I’m willing to volunteer my place, be aware that there’s not a lot of parking (though there is street parking available) and people would need to bring their own chairs. And I do have the Wii ;). But there is likely a better location available somewhere around.
