Wayne:
  Now there's a thought that didn't occur to me. They may be running me
all over creation for some reason rather than taking some more direct
route. Perhaps they ran out of somthing here in Michigan and had to run it
down to Texas and back to get it connected correctly. I think I'll have
them inventory the path and let me know what it is.

Thanks to all the responses on this.
