I recently discovered a Yahoo! group dedicated to bringing Corgi owners around the Minnesota/Iowa area together for a Corgi picnic in June (it's far off, but people in the Midwestern US states need warm thoughts for the Winter). Perhaps others know of it or have even attended. The link to the group is:

The picnic takes place around June at a location central to Minnesota and Iowa residents. During the June 2006 picnic, $380 was raised for Corgi Aid and attendance was ~34 humans and ~30 Corgis.
I hope other members of the goCori community can make it to next year's picnic!
