Bears at #37? Maybe.... But I have had more problems with mice there. #37 is a huge campsite so getting a spot for hammocks would be no problem. But it also can be a crowded campsite, so arrive early for best campsite selection.
#47 is a great site, but I agree with HooKooDooKu.... not great for hammocks. I spent a very uncomfortable night there stretched between two trees that were way too close together for a proper lay. Beautiful site otherwise. It has been several years since I hiked through there. Does anyone know if they ever replaced the bear pole with cables? I had a very hard time getting my food bag up on the pole last time I was there and finally ended up hanging my food bag under the bridge over the water.
