Had a frigging dog chasing me once... hit this hill a few times and at the end of the run this dog on his leash would go nuts I just turned around every time and kept going. My last time down he broke his leash and chased me down the street. I just knew he was gonna trip me up or take a bite outta me but he couldn't catch me thank goodness. Had to go somewhere else though. Perfect hill too, long downward slope after a steep start and a sweet curve that ended into another short rise so you could slow down and then use the short rise to get a good ways back without having to walk up the whole thing. On a dead end street with no traffic...stupid dog!
