no need for a hack saw, yes all the old rails are locked up but there is a 30 ft. flat box thats 21/2ft. wide, there is a flat down kink box thats 2ft. wide and is a little biger than the flat box, and they have a 3rd box which is a up flat down that would be the best to session, the only thing about it is that you need at very least 3 guys to move them. 4 or 5 peeps would be ideal. And just to add one more thing, i was invited by Matt Gormley to hit the boxes pre-season, so there souldnt be any hassel with the any workers. See you up there PEACE!!!
