North Dallas Gathering?

I've been wondering, off and on, if any of my friends, iFriends and/or regular readers would be interested in getting together for an afternoon of helping me pretend to have a social life. This was inspired, in part, by some of the get-togethers that have happened when Accidental Historian was in town, except that I'm trying for a venue where people can actually talk to each other. (I've had a lot of fun at those things, and they've kind of reminded me that I really don't Just Go Hang Out With People enough.)

Here's what I'm thinking:

Time & Date: Saturday, October 13, 1:00 - 5:00 p.m.
Location: Either The Londoner in Addison, or else Trinity Hall at Mockingbird Station off Central Expressway (Highway 75).
Who's Invited: Anyone who's in the area (or happens to be passing through) and thinks this sounds like fun. Children are welcome (mine will almost certainly be there) though neither of the suggested locations are really set up with kids in mind.

This is all pretty tentative, so let me know what you think. Is there a better place? A better date? I like the mid-afternoon time, because A) it shouldn't interfere with anybody's dinner plans, and B) those of us who have kids can get them back home with plenty of time to get ready for bed.

If you're interested in attending, leave a note in the comments. Even if you don't have any particular suggestions, it'll help me to figure out how much (if any) interest there is for a gathering like this.
