Brutal hill!! Been riding it for years. Start from Piermont and ride straight up to 9W then head North to OMR. Go up then hang the left then up again. Once up there you can do the 6 mile loop up there. I will do this little loop when i feel like killing my legs. Funny thing is i tried to map it on MapMy Ride and it only shows it as around a 6% incline!!
