If we went in April it would need to be the second week. April 7 - 11th. Not sure I could drive all night Sat night and hike Sunday but we could always meet there Sunday at Amicolola Falls State Park. ($5 to park you car in a safe lot) Doing the approach trail from the state park to the top of Springer where the AT starts would add an extra day but save a $50 shuttle fee. Springer to Neels is 32 miles. Figure 10 miles a day would be good on this part of the trail.
