These calculations demonstrate that the scars of periodic orbit model is seriously flawed. An alternative picture of localization in chaotic regions is outlined.7 pages, Postscript type, 3 Postscript figures available at ftp://dirac.tcg.anl.gov/pub/davis/ (fig*.scar.ps)Chaotic DynamicsDifficulties with the Scars Model of Quantum Localizationtext
