Ch. 11 had a special on the other night that was really good. I'm sure it will be repeated so if you have time try to catch it.
Two points that I was surprised by 1) The canine distemper outbreak in our area, approx. 2 yrs. ago, may have been caused by racoon transmissions and 2) their droppings are extremely dangerous because they contain eggs that can become airborne when swept.
Check it out, or not.
