Practice out to 50 yrds.and take a rangefinder. Water holes will almost always garuntee a buck or atleast a sighting.... Take agroundblind and a comfy seat.

also find some good sources on how to judge them. Its easy to see one and think its huge but then when you score it, it ends up low. (obviously if your interested in P&Y) Height & widthgives you the most points, my P&Y buck didnt have much mass, but was really tall.
