Par for the course out here. During off-season and the archery season, our deer are pretty mellow & easy to stalk. Heck, before turkey season, when the deer are still down low, I can usually get 40-60 yards away with the wind at my back before they spook. I snuck within 7 yards of 3 does during the archery opener (can't shoot them out here). But the couple occasions I've gone out during the rifle season this year, it hasn't taken much at all to put them on high alert. The slightest movement or gentle nudge of wind in the wrong direction puts them running out of there at 100+ yards out. Mind you, I'm 1-3 miles from the nearest road. It's like a different personality of deer. I'm pretty sure the sound of gunfire changes things.
Last year, I think my buck just didn't get the memo and let me walk right by him at 30 yards (rifle hunting). Calm & cool as a cucumber. But that was a strangely fortunate event -- not the norm. His careless genetics are now out of the gene pool.
What to do? Stay home or keep trying. It's impossible to be successful at hunting sitting at home. Statistically, if you keep trying, you eventually get lucky.
