The list of GF cereals seems to keep getting shorter.  The only rice cereals
I feel fairly confident are GF are those marketed by ENER-G (800-331-5222).
 They make a crispy rice cereal & rice nuts.  Edible?  I guess it partly
depends how determined you are to have cereal...but as a former cold cereal
addict I think they are ok.
