Have not seen any reports but here are some top of hear thoughts:
* Down the Pee Dee and then bike around Uhwarrie
* Near Hot Springs, NC there is a sub24 that is along the French Broad and Painted Creek Campground.  I suspect there is more to explore on the roads all up around that area
* The New River is good for rafting but not sure of the riding in the area

Subject says it all.  Looking for a framebag for a XL Salsa Timberjack.  Bought in Jan 2017 so i think this is the 2016 which is the first year.

I have used HDPE from Tap Plastic for some of my items.  Not sure if it will work for you: https://www.tapplastics.com/product/plastics/cut_to_size_plastic/hdpe_m_m_opaque/258
