You do not have to be 16 feet up in a tree, all that does is increases the angle of the shot making it more difficult to make a good shot. My permanent tree stand which has the top open is 10 feet high and I have shot deer almost under it and a couple 8 or 9 feet away. Additionally, lots of deer are killed by hunters on the ground. You also don't have to take a pee bottle either, urine is urine to a deer and they just may investigate it if they smell it.
