Don, Up until a few years ago we called it switch cane(Arundaneria tecta) but it was re-designated as hill cane(A. appalaciana) for the higher altitude stuff. It is actually deciduous and has thicker walls and a rounder culm than switch cane or river cane(A. gigantia).
Glad to hear you are coming to the Classic. There will be lots of folks there with "primitive" equipment. PA is a sponsor and PA members from all over are planning to come. It will be our(PA) biggest contingency to date. We had over 30 folks last year.
