Thanks for all the input.
I've made dozzens and dozzens and more dozzens of shoot arrowS. All kinds exspecially dog woods and have made and store them all in my shop some for years. These wer'nt new first year shoots these were 2,3 year old shoots maybe older. They'ed been seasoning pushing a year. I've make dog wood shafts thats seasoned less. Dog wood makes a fine arrow shaft. I'VE BEEN MAKEING THEM 14,15 YEARS. After staighting,sealing dog wood stays straight. I've store them in my shop bitter cold straight through to hot,hummit summers here in WV. FOR YEARS NEVER HAD THIS HAPPEN BEFORE.
THE ONLY THINK I DID DIFFERENT WAS WHEN I FINISHED THEM I HAD OTHER THINGS TO FINISH AND SEND WITH THEM. I packaged them in 2 inch pvc pipe to send them in. The first time for pvc I've always used cardboard tubes. In all ,by the time I'd finished put trade points on them and stored them to he got them was a couple 3 weeks.
I THINK MAYBE BIGFOOT GOT AHOLD OF THEM AND DID IT OR SOMETHING.
