Agreed. Those who have experience in the outdoors know that even a simple wrong step and a fall can potentially be deadly. At this time of year, temperatures at night can still be a challenge for someone who has no way of keeping warm. Always go with a buddy, imho.
Here in upper East Tennessee it is going down to the upper thirties tonight, and breezy. Wind-chill factored and we get below freezing effect. In the Mountains it will be frosty tonight!
