Howler has it right here. As a buck gets older, his home range will get smaller. Especially if he has bedding, water, and a food source all in close proximity. To hunt these mature bucks you need to get as close to the bedding area as you can without spooking them. Sometimes this means not hunting mornings in these stands because you will spook the deer trying to get to your stand at the same time their going back to bed after feeding all night. Wait till evening, so you know the bucks are bedded down. Slip into your stand as close to the bedding area as possible without alerting the deer, and then hope they get on their feet before the light fades. If you hunt too close to the food source, by the time they get to you it may be too dark to shoot, or you may already be back at your truck.
