Every January
Every January for the last few years some friends and I have gone and camped along the Appalachian Trail. It's you can park at Pine Grove State Park and then hike your way into locations or park at other trail heads. Water is easily found and views like Sunset Rocks are simply gorgeous. These trips are what gave me the experience, and confidence, to go from tent camping to tarp camping.
