Both. Tree stands work and so does hunting from the ground. I killed my best buck ever sitting on the ground with no blind. I have killed many deer this way.
Look for trails. Look for White Oaks that appear to have frequent visitors. Acorns from the White Oak are always going to be the favorite food source of Whitetails. Look for trails and cracked acorn shells around the White Oaks in your hunting area. They will also eat acorns from Red Oaks but they prefer the White Oaks. Later in the year they tend to feed on any browse they can find because that is all there is left. That is why so many guys plant food plots. Look for bedding areas and the trails leading to and from them. Setting up between bedding areas and feeding areas are the best way to hunt for the early part of the season and perhaps the later parts of the season. During the rut it can be anybody's guess but your best bet is to look for does and their bedding areas during the middle of November. Stay quiet, try to be quiet going in and out of the woods. If you snap a branch in the morning going into the woods and a deer is bedded 300 yards away on another ridge, guess what? They can hear you. Always use the wind to your advantage. If the wind is in your face, you are fine. I will not hunt an area if the wind isn't right. I would rather stay home. If I can give one piece of advice to any beginning hunter it is watch the wind. A deer's nose is their best defense and if they smell you, bye. Game over. It may sound crazy but wash your hunting clothes in scent free detergent, store them outside in a container. Keep your boots outside and do not put them on until you get out of vehicle to hunt. Don't wear them to Waffle House or while pumping gas. Use scent free soap and shampoo. This may sound extreme to new guys but believe me you can never be scent free enough.
Just some easy tips for beginners. You can hunt and kill deer if you are patient and careful. Be safe and good luck.
Great thread!
