Bingo!  Can't believe I missed that.  Our upstream has added the PTR.

Also, someone else told me to turn off the HostnameLookups option.
It was on for somereason.  (I did not setup the box)

And I stripped out all the zones in named.conf on the old box which
turned it into a caching name server only.

Things look good now!
