I am planning a trip mid-March to Virginia. Our options are central or southwest. We are planning a 4 day trek. I was looking for some advice on a section to complete where parking is available at each end. Also, how about the weather? Too cold in SW this time of year? We are planning to complete sections of VA each spring and fall. This will be our first section and first time on the A.T. Help us make our first experience a good one. We have previously hiked Linville Gorge, NC so we can handle the terrain.
