I shot for 10 hours straight last night, I know for a lot of you thats no big deal but I usually only get to shoot about 2 hours a week if I'm lucky. I was in a ring game for about 5 hours then me and one of the guys from the ring game shot heads up for 5 hours. I'm only 37 years old but when I woke up this afternoon my back was killing me. Anyone else here ever feel great while they were shooting then later the ton of bricks hits you?
