Nope; he didn't bother with mentioning them since those particular sinkholes were already mentioned (in detail) in other Railway Age articles and elsewhere. He's definitely on the side of the railroads and operating agencies, anyway, and now that the FCC has finally got its thumb out of its derriere and actually done its part (as it should have done three or four years ago, rather than waiting until six months before the friggin' deadline; ah well, that's Washington for ya!) perhaps this JOATMON might be made to work (please note that I specifically did not say it would work well, if it works at all). I wouldn't bet on it, though...
