While this guidebook is still the only printed source for central Texas limestone, it is extremely outdated. Do not get me wrong, for those wishing to merely sample the limestone of central Texas, this well established guide will lead you in the right direction. However, with the innumerable number of sport routes and bouldering areas that have developed over the past five years, this guide is in need of a serious overhaul. As well, it is DEFINATELY not worth more than 15 bucks! Better to look at Blodyflapper.com or Texasclimbers.com for up to date information.
