glad i came across this. friend of mine gave me three to try, and though i haven't fletched them up yet they seem like primo shafts. i had no idea what the stuff looked like, and this prompted me to figure it out. turns out i got this stuff growing all over, and i've looked at it and wondered often. now i know. so i went out this afternoon and cut about 3 dozen shoots and a few that may become atl atl darts.
