Gene, I must lovingly chastise you! I've been to the Billy Ireland and it's something each and every one of us should do. Last week was Cartoon Crossroads, their once-a-year celebration of all things comics-based. It's got academic componants, artists who are in the news (the year I went, the big guest was Garry Trudeau -- this year it was, I kid you not, Olivia Jaimes's first public appearance), and artists whose work is far more popular than any of the stuff we worry about here (Raina Telgemeier). Also there's art for sale, mostly local artists, so if you're a Bone fan, you can find work by him you won't find anywhere else.
Beyond the festival, there's the museum. When I was there they had Calvin & Hobbes and Little Nemos on the walls. That people could look at. And if you or I made an appoinment with someone like Jenny Robb, curator, she would give you a charming tour of those archives, and you can look at all the Caniff and Watterson you could imagine.
If you were saying Ohio is out of the way, you're right. But it's not just part of a giant archive -- it's on display frequently. I encourage everyone to visit.
