I've got two tips that have proven themselves over and over again for me. The first, do not contaminate your hunting area with scent before season. If you run trail cams, make sure that for the last 3 weeks before season, that you are scent free when you go in to check them. I see alot of guys go out and check cams right before season in their jeans ans work boots, get alot of good pics, then wonder why no deer are there when it's time to hunt. If they are not regularly exposed to human scent, the scent you leave behind checking cams can scare them away from an area, or make them go nocturnal for 2-3 weeks.
Tip number 2. If you have taken or seen a good buck in a particular area or on a particular trail in years past, keep hunting that area unless something drastic has changed the landscape. If you took a good buck out of one stand last year, chances are VERY good that another good buck will be there this year. Big bucks like the same things, so if one is removed from the herd, another will step in to take over his ground. I have shot 4 P&Y bucks from the same trail in the last 4 years. 3 of them from the exact same tree stand. You know what stand I plan to hunt most this year. lol
Last thing I'll say is, be as scent free as you can be. Even if it's just a spray like Dead Down Wind, or Scent Killer. Watch for bargains in Cabelas, Sportsmansguide, Bass Pro, and buy the stuff in gallons, and use it. I personally like Scent Lok suits, and still use the spray on everything. Bottoms of the boots are important too, not just the tops and sides. Using a Scent Lok suit, and spray, I have had a buck as close as 3 inches. Yep, inches. And he was downwind. Not a big buck, but any deer at that distance tells me something's working. I know someone is going to call BS on this, but it happened. Just never got a chance to get a pic of it.
