I don’t know what, but something’s growing.  It came from our compost, so there are several possibilities. My first impression was zucchini, but it’s looking a bit bulbous for that now.  My hope is acorn squash, although it doesn’t have the signature ridges of an acorn squash…yet?  Maybe it’s summer squash…enormous zucchini?  Whatever it is, the guessing is more fun than the waiting.
