So my mom found these tracks in our backyard. We don't live in the woods, we're smack in the middle of suburbia, and we have a fenced in yard. Whatever it was came from the street, climbed the fence, ran across the yard and the tracks stop at a tree.

I posted on Facebook and asked everyone what this beast could be, I've gotten back grizzly, deer-bear, dear, buck, possum, wampa, rabbit, cat, cougar, werewolf, red fox, grey fox....

What do you think it could be? I'd love to see some flash fiction or poetry showing your ideas! Please leave in the comments, or comment with your link!
