RE: coyote problem
If you ever in your tree stand and see a coyote, but it's just not close enough for a shot, use your lips and making a kissing sound. You'll be able to see it's reaction, and it doesn't take much to bring one in to investigate. Only make enough sound to get the coyote started in your dirrectin because if it pin points the sound up in the tree, it will bust you and be gone. SO, make just enough sound to get it to come looking and shoot 'em every chance ya get.
If the problem is out of hand, contact your local ADC guy and have him/her trap them for ya. Traps, done correctly, will catch way more coyotes than huntingwill ever kill.
