There will be a B-29 and a B-24 at the Carolinas Historical Aviation Museum at Charlotte Douglas airport.  They arrived yesterday and will be there through Sunday night.  It's open from 9am to 6pm and there is an admission fee, I think it's $15.  They usually sell rides in the B-24 as well.  The B-29 is the only one in the world that is still flying.  If anyone is interested, stop by and check it out.  I'm going to be there on Sunday afternoon.
