I think this thread is posted in the wrong area...should probably be in "Best Practices"? Anyway just wanted to comment on the following..
A typical big deer tactic is to bed just below the crest of a hill or ridge if the wind is coming over the top at their back. They can see downhill, and at the same time keep tabs behind them with their nose
I saw this in a show and then saw it first hand last week when I did some in season scounting along a ridge top. It actually started out as a still hunt but my patience got the better of me and before I knew it I was moving quicker and being still less...and of course that led to jumping what was an impressive 6 or 8 pointer who was just below the top of the ridge..looking down the ridge with his back to me..and yes I was hunting with the wind..another still hunting mistake, but like I said I was scouting and threw stillhunting in half hazzardly.
My recommendation would be to set up near the field but inside the treeline perpendicular to where there is a well worn trail into the food source...for a PM hunt you can ambush them when they are on their way down to feed in the fields, just ensure you hunt that spot when the winds are in your favor...for an AM hunt do the reverse and find a spot further up the ridge, again perpendicular to a well worn trail, maybe half way up between the food source and where they are bedded down.. be prepared however to not see a typical big boy until later in the morning. During the rut its highly likely that the big boys are chasing does just inside the woods and checking scrapes on their way back to the bedding area...if you find a scrape line along that trail so much the better, set up near, but not on top of it and wait. Best of luck...sometimes I think I enjoy finding a good ambush spot with good sign nearby almost as much as shooting them...its all part of the experience!
