I have a bunch of used deck boards and lumber for free. There are 16 2x6 15 ft long pressure treated boards. There are some redwood deck 2x6 boards about 9 ft long. There are other shorter pieces of 2x6 pressure treated boards about 2-3 ft long. There are some 4x6 redwood posts. Take whatever you need. Boards would be good for concrete forms or whatever.
