There's a get-together this Saturday in Green Bay, Wisconsin. It looks like about a dozen cars or so. A bunch of Illinois/Wisconsin folks are meeting in Milwaukee and caravaning up. Go to the Focus Revolution section and read the threads "Sept. 26 - Oct. 1" and "Oct. 1 Caravan to WI" for details. Yeah, I know, it's a ways, but it's this weekend anyway.
Don't know, but keep an eye on the Focus Revolution section. There's a group from the Elgin/Shaumburg area and they do meets once in a while. I think FR usually does one big one each year, it was Focus in the Field earlier this year in Harvard. You can always post up a dinner or whatever in Crystal Lake too and see who bites.
I'd be up for a g2g in Crystal Lake sometime. I saw a red SVT at the Woodstock Walmart and a silver SVT with a fart can by the square so there are Focuses here (Foci?). Lots of newer ones too, but I personally tend to notice the old hatchbacks more.
