³ÉÈËÂÛ̳

WOSU is not one of the NPR stations that usually broadcasts WHYS, but for this one-off programme they're not only putting us on the radio but on TV too. A spruced-up Ros will be joined by .

If you'd like to join the audience - or just tell us what we should talk about in Columbus - send an email to worldhaveyoursay@bbc.co.uk.

As usual on location, we'll be asking the studio audience what they want to talk about. (You know that we ask you every day.) But one of the topics we almost undoubtedly will be covering is .

March 20 marks the fourth anniversary of the invasion of Iraq by the US-led forces that overthrew Saddam Hussein. There'll be a lot of coverage on the ³ÉÈËÂÛ̳ that week - it's already been declared Iraq Week in our schedule (following on from last summer) - but what would you like to hear?

WOSU has close links with , which holds the staions' licenses, so perhaps you would like to talk about the cost of tertiary eduction, or the role of sports in college life (on the Sunday before the show, there will be NCAA basketball championship games at the university - I'll be arriving too late to see them, which makes the fact they are sold out a lot easier to take). And Ohio is a key in US politics - is that something we should talk about? Ohioans certainly reflected the national mood in 2006, electing the anti-Iraq war Democrat Sherrod Brown as their junior senator over the Republican incumbent Mike Dewine.

Just a few ideas - tell us yours by posting a comment below.
