I haven't tried 'coon myself. One of our dishwashers, years ago, brought in a cleaned 'coon and had us cook it in the smoker for him.
Of all the diseases that were mentioned in the comments of that article, the one that should really make people concerned about their 'coon is trichonosis. Animals get that by eating trash. That's why pork was also supposed to be cooked "well done", to kill the trichonella worm. But, bear meat and 'coon meat also needs to be cooked extremely well, to kill off the same worm.
I really like how they described the cooking process, two hours parboiling, then roast or smoke the critter.
I live out in the sticks, and have a large wooded area just across the street. I have yet to have my garbage invaded by anything other than the dogs down the street. We notice more coyotes than anything else.
Squirrels are even easier to take care of. Steel-toed boots, a jar of peanut butter, a slingshot, and a bag of marbles. Heck, that's legal inside city limits! Just make sure you have a hunting license.
