    R Dude, Dr. Asphalt has had a rough time as of late. Seems
    that Daubert is kicking his ass on more than a few mold
    cases. I wonder what is left for him as a “professional”
    witness. One would believe that in order to survive as
    a “professional” witness, one would have to substantiate
    the “professional” part no matter what one thought of

    Perception is not reality when it comes to Dr. Asphalt.
