Lower Sheep Pasture from Nichols Rd to the golf course and most of Upper Sheep Pasture have been stripped and will be repaved hopefully soon. Many rides leaving from Stony Brook use these roads, so avoid them until further notice. Unless you have a mtn bike, then enjoy. You can still use Lower Sheep Pasture but you will have to take 25a to Bennet's (CVS) to get past the current unpaved road. I will keep you updated since I live in the area.
