Just a heads up. I was waiting to list a archery long bow I purchased at a garage sale on ebay. Problem was finding a strong 6ft tube. I did the drives through the back of strip malls and found squat. So I went to home depot and was walking around and TA DA. In the carpet section next to the rugs on rollers section, there were plenty of cardboard tubes that the carpets were rolled on. They are 4.5 inches in diameter 15 ft lenghts and super strong, 1/4 in thick. Manager said take them all because they are headed for the trash.
