I hate posting third party events in the Corner because it encourages a deluge of press releases from P.R. types across the country. Nevertheless, some deserve it. For example:

Social Security: Is It Really a Crisis?
A free public debate in New York City
Tuesday, 15 March 2005 – 7pm-8:30pm
New York Society for Ethical Culture
2 W 64th Street, New York, NY 10023
(on the corner of Central Park West)
Featuring Michael Tanner, Director of Health & Welfare Studies, The Cato Institute, and Paul Krugman, author and columnist for the New York Times.

I hope C-Span covers it.
