Sissons in Springfield

Why is it that most of the family reunions listed by the National Genealogical Society are elsewhere than the Midwest? Here's one slated for Springfield (Sangamon County), Illinois (I have relatives with this surname but no ancestors):

SISSON - The 8th Biennial Sisson Gathering for all individuals researching the name of Sisson will take place 26-28 June 2008 in Springfield, Illinois. Sharing of Sisson genealogical records, discussing the Sisson DNA project, and displays of Sisson family charts will be among the featured items; tours to local Sisson historical sites will also be arranged. To receive an Announcement and Registration form, contact David Martin at davidchina_2000@yahoo.com, or call 508-420-0224.

Calling All Klopfensteins

And, speaking of Allen County, Indiana, a worldwide reunion of the descendants of Elmer and Lois Klopfenstein and allied families (including other Klopfenstein branches) is set for 20-21 June in tiny Grabill, Indiana, ten miles northeast of Fort Wayne and about the same distance west of the Ohio state line. "Not just a family meal" but a "planned program" is promised.

I'm impressed that Rootsweb's Worldconnect project shows 9495 entries under the surname. Even allowing for many duplications, there surely could be enough Ks around to multiply the normal population of Grabill by several times.
