Okay I don't want to come off as some tree hugging sissy hippy but I want to encourage everyone to recycle shelving and wood as much as you can. Old barns, home remodeling, even old shelving from other places. No point wasting something that can be fixed up. For example when my grandma went into assisted living we prepped her house for sale. After the estate sale we tore down all the shelving she had and i got some really good 40+ year old wood planks that would cost at least 40.00 each if you can even find stuff this nice. Alot of salvage yards have wood salvaged from barns, homes, garages and such as recycled hardwoods is big bucks in houses these days. Even scraps from a lumber yard if you can find them or talk to cabinet makers and such.
