This is a picture out of my second story window (facing our backyard). That's a pumpkin vine. This pumpkin has been slowly devouring our neighborhood. I found one tendril making its way into the yard of the neighbors to the south and another headed to the north. I curled both of those around back on themselves and now its headed for the roof. The cool thing is that this vine is sporting a pumpkin half way up the wall. That ought to be fun to harvest.
