As for the coyote problem, you are entitled to deal with it. If the suburban tricks like a fence or stay in after dark don't work for you, you have the right to discourage their interaction with your family and pets. You can pick up a cheap/used .22 LR rifle for varmint control that won't make your back yard sound like a battle zone but gives you the power to reach out and touch the rascals.
I'm a nature lover too, but growing up in "the sticks" near many wild and domestic animals, you just have to accept the balance of nature now requires human interaction at some level. On the other hand, perhaps this level works best for you:
And heck, who does not like mounting a $12,000 night vision scope on a military grade rifle to...clear the cobwebs from the brain?
