Dave, I've been bowhunting for over 25 years and for the last 20 I've been fairly sucsessful. I concentrate on food sources early in the season. The area I hunt has alot of cropfields of corn and soybeans and also plenty of apple trees and oaks. So locating the right food source on a given day can be difficult. My stands are set up early near these areas and I just hunt the ones that seem to be showing the most sign with the wind direction in mind. Later in the season, when scrapes and rubs become evident I concentrate on those areas, usually spending the most time where the rubs and or scrapes are in bottle necks or near doe bedding areas. It helps I suppose to have hunted the area you hunt for a number of years as you will start noticing patterns the deer use. I know on my ground the deer bed and feed in virtually the same places year after year but suttle changes in the habitat like blowdowns, absense of undergrowth and poor acorn crops make them change sometimes. Different crop plantings do to and you have to continually keep up with them or better yet try to stay a step ahead.
