Yep, distressed lumber has become quite a hot commodity. The more fucked up it is, the more it's worth. Which is the reason I now use a hatchet in conjunction with my 32 oz framing hammer while installing interior woodwork. Gives the homeowners a sense they're going to get their money's worth, even if it costs every last dime.
Enough about quality, when I was about 10, dad found a barn to tear down and clean up for the lumber. Free. We salvaged many of the nails also, which led to blackened fingernails, bloody hands, tetanus shots, and finally, the skill required to drive a bent nail through 100+ year old oak at a 45 degree angle.
Work? I've got at least a years worth in the pipeline, but I can't afford to go out and buy a barn for the nails nowadays. Have you seen the prices on barns?!? LOL
