Craig,

Hey if Mr. Celko happens to reference any online references to this topic in his talk can you post them here? We are doing a couple of tree structures in SQL and VFP and it'd always be good to see his perspective.

>For those of you in the Salt Lake City area, mark your calendar for Tuesday, April 13. We'll have a very special guest speaker, Joe Celko. Joe's topic, "Trees in SQL".
