pressure starts the minute you walk in a deer's woods!No matter what your in the woods for... weather it's a walk or hunting or checking your cam's when your in a deers house there one pin's and needles!My new hunting spot I got is heavily over populated with deer,when i put my cam in last week deer stood there and looked at me but I guarantee they were on pins and needles. These deer are use to humans but I thinkwhen I went down in the woods they were a little jittery.
