How to sneak up on Deer
Scent cover is a must to sneak up on all the deer I have done tests with it on and 
off it makes a big difference!

Tree stands
When you're in a tree stand and want to get out, look down at the ground first then 
get out. If you don't look down you will be killed from the fall.

Drawing them in
Get a deer feeder and a treestand and get to a thick area with lots of trees and get 
a call doesn't matter and start calling this may take a good bit of time but it is well 
worth it. it is way better then chasing a deer around. oh and doesn't matter you 
can use a bow or a gun

Improving Stats:
Stats will improve as you progress through the game, based on your use of the 
skills associated with those stats. For example, using you tracking skill successfully 
during the game will result in your tracking skill improving, excellent shooting 
improves accuracy, sneaking up on deer improves your stealth, and running 
around a lot with a heavy pack increases your strength. 

Crouch Warning:
Do not use the tree stand, tripod, or ground blind while crouched; you will die 
when you attempt to exit.

Recommended Deer Hunt Locations :
The best place to hunt deer is Arizona. You need the buck decoy, buck call, scent 
cover, and the urine scent. First, use the decoy. Then, use the scent cover and 
urine scent. Finally, use the buck call. You should have bucks coming in a matter 
of seconds.

Attracting Deer:
Get a deer feeder and a tree stand. Walk to an area with a lot of trees. Set up 
your tree stand and deer feeder. Get up in the tree stand, use the scent cover, 
then use your buck call. It may take several minutes to attract a deer. For best 
results, use your rifles.

Easier Aim:
When you are hunting with a bow or any other difficult to aim weapon, equip 
yourself with the spotting scope. Zoom in and line its crosshairs up with the deer. 
Then, switch to your weapon. If the deer has not moved and is in range, your shot 
should be dead on. You can also aim the scope a slightly over the deer to adjust 
for the drop in the arrow (or bullet). With some time and practice you will kill them 
every time with this technique.
