I'm gonna guess the mice did that because of the move towards more recyclable goods. You know, like your car's wiring. Yes, they love the covering on the wiring. Insurance covers it, the first time. After that, the thousands of dollars of repairs are yours.
Might be cheaper to go with a live Christmas tree, of course we are partial since we sell them. They are a crop grown for this purpose, not taken from the wild. The key is to go to a farm and cut your own, the trees in those lots were cut months ago, that is why they blow needles all over right at the start. Fresh trees don't do that.
Our tree? Um. Welll, not up yet. Sold plenty though!
