Pressure could be part of the problem, but being in the right place at the right time has alot to do with it as well... Deer are moving durning daylight, maybe not everyday but they are moving at times... Trick is to be there when they are moving... If you are hunting right on scrape line or rub line chances are they are coming at night to those spots, so you are not going to see deer... Try hunting trails leading to bedding areas this time of year. where I hunt we have 2 huge pine thickets, and what I do is, take me climber and head into the woods and just start walking around these bedding areas, maybe 100 Yards off maybe more if it is a calm day and I think they can hear me. and I just walk until I find a good trail, maybe a rub or scrape, then I will play the wind about 20 yards on the good side of the trail and follow it back to within 50 Yards of the thicket... and setup shop... Being as quiet as possible... and using a climber you can only be so quite but this has worked great for me. I got an 8 point last week, and I have seen alot of deer... This has been working for 3 years for me... give it a try sometime, I think the trick is that the deer have no time to change their patterns. Meaning I have not been in there and setup a treestand or scouted or anything... I just showed up, on the good side of the wind and they have no clue until it is too late... Also one other thing, I use 18" rubber boots, with a strong cover scent on the bottom like Coon urine... This works great should you walk where deer happens to walk... I have had deer brush up against the tree I was in and no nothing was above them...

Just thought I would give you my 2 cents... Good luck!!!
