Several suggestions were made. Personally, I'd love to get Phil Plait(bad_astro), 'cause, well, I like astronomy best of all. But in discussing this, I also mentioned a certain PZ Myers (pharyngula)... It seems that PZ has agreed to come! Now, biology isn't really my thing, but how cool is that!? Somehow, we have to defend ourselves against the tarnishing that Scott Adams is doing to Mensa's good name with pieces like this.
I claim none of the credit for this success, of course, since it was our great, fearless leader Linda who got the "yes" out of PZ. She wasn't quite as successful with Phil, but she sent the powers that be after him... and maybe PZ will be a little enticement? ...or maybe not.
But now it looks like I have to plan a drive to Denver for next summer since, obviously, I can't suggest such a cool speaker, get him to go, and then not go myself. Anyone know of any good routes to get there from Columbus, in say, less than 26 hours, without taking the horribly dull I-70 corridor through Kansas? Been there, done that before; don't need to do it again. If you've seen Kansan wheat fields once, ya know... I'm sure I can come up with something if I look on my big map, or talk to AAA, but I don't have that in front of me right now. 6 days next summer... could this maybe even be called a vacation?!
