The saga will consist of, 1) hire professionals to look at the problem. 2) Freak out at how much they estimate it will cost to fix the problem. 3) Let them deal with it, and don't pay any attention to what's going on besides that, because there's absolutely nothing I can do to affect the outcome. 4) Pay the amount of money which will be even larger than the original estimate. 5) When the raccoons come back, call the people back, who will have warrantied their work, and have them fix it again.

I am NOT going to match wits with a raccoon. I will let the PROFESSIONALS, who, presumably, have done this before, and even have won occasionally, match wits with a raccoon.
