What is Purgatory?

For this podcast, I'm giving you a live presentation that I did at Incarnation Catholic Church in Collierville, TN for their RCIA.  It's a short answer to a question:  What is purgatory?  I didn't include the questions and answers afterward, but I did give a couple of comments after playing the presentation.  I hope you enjoy this.  Hopefully, I'll do a few more live ones in the future that I can post here.
