Mr. Sandoval's Poles

Mr. Sandoval's Poles are poles in Mr. Sandoval has in his yard so the plower will know where the pavement is, which he does before a snowstorm. Once, Greg Heffley and Rowley Jefferson plucked the poles out and fought with them, saying things like, "En garde!" and, "Yaaargh!". But Greg says the must've not put the poles in the right place, because the plower was off by about 10 feet.
