I'm contemplating hiking a short section between Christmas and New Year's. I'd be starting in Damascus and ending I'm not sure, maybe Sugar Grove. Has anyone hiked this section during the winter? I definitely need a warmer bag. Mine is only 30 degrees. The coldest I've hiked was over Thanksgiving in the Hot Springs area. Any advice or experience on this? Been looking at bags for a while. Any suggestions that don't cost over $300? Thanks all.
