* Safety is always the most important aspect to keep in mind. Nothing matters more than firearm and tree-stand safety. And ALWAYS identify your target as a legal deer before putting your finger on the trigger. Never consider shooting at sounds in the brush.
* Talk to landowner about deer patterns and locations. He probably knows where the deer travel and gather.
* Always wear a safety belt or harness while in a tree stand, and never climb into a tree with a loaded gun.
