There are a lot of factors that influance hunting areas where elevation from ridges or ravines come into play... Bucks bed in pretty predictable places along ridges and a quick look at a topo map and you should be able to pin point primary buck bedding without ever stepping on the property... Besides bedding, you need to factor in thermal wind currents when hunting this type of terrain. Thermals and wind direction also influance buck movements and bedding... I actually produced a 3-1/2 hour tactical DVD that goes into great depth about how to hunt deer in that terrain, and how to look at a topo and know where they are bedding. Its called "Hill country bucks" and its available in the store on my website www.huntingbeast.com
