Glad you had a nice hike at Greylock. We are about an hour 1/2 from there and have been to the Mtn many times. We have stayed at most of the shelters there. If you don't like the idea of using the road there are various ways up to shelters or to the BPers campground. We have parked on the Western side of the park at the Haley farm area. There are 3 trails in from there. Also on the Western side of the park off rt 7 there is the roaring brook trail. For a quick overnight the BPers campground isn't a bad place to stay. There is plenty of downfall wood for a nice fire. In the last few years they have added bear boxes to all the shelters we were at. The only thing is I cant vouch for the roads into these parking areas in the winter or if the trails will be useable. We usually go in the spring or fall just before the snow comes. You can get a lot of info on the States Greylock reservation web sight. If you need any local knowledge I would be glad to help if I can.
