The North Carolina date has not been officially released.
Originally it was listed as Raleigh but now it is Raleigh/Charlotte region.
Based on the Atlanta event being in Dahlonega, GA about 1 hour north of Atlanta at an off-road location, my guess the North Carolina event will be in Troy, NC. This location is between Raleigh and Charlotte and is home to Uwharrie National Forest that has an off-road trail system and there are 2 other private trail locations in the general area as well.
