The back of our Great American Hovel™ has what was once apparently a well, but has now been filled in, very much with the shells of pecans.
Guess who likes to nom pecans: if you guessed Our Praline and Our Chuy, you'd be spot-on.
Soon I'll gather all the beggars up from around the yard and burn them in the chimenea. So far have only seen one which looked edible, so it's very much not worth the effort to try to salvage them after spending a winter on the ground. Teh puppehs on the other hand, seem to not be picky at all about their pecans.
