Nice target, especially for aluminums. If you shoot carbons into it, please use soap or some other type of lube on the business end of the arrow.
I made a target out of the blue insulation foam left over when I finished out basement. The first arrow I shot into it, I had to flip it over on the back, stand on the target, and use both hands to pull the arrow out. Still almost busted a gut![:@]
