Ever since we moved in this house last year this tree has perplexed me. During the house hunting, before we bought it - I saw a racoon coming out of one of the holes. The thing is HUGE - it may not look like it from the picture, but I am waaaaaay up a hill and when you go to the bottom of the tree - it is large enough around that my husband and I together couldn't wrap our arms around it. It has lots and lots of "holes" and nooks and crannies. Any ideas?
