Almost all redwood lumber now comes from farmed groves, and I tend to contemptuously refer to the marketed product as "pinkwood" because it is so much
less dense than old growth redwood lumber. The hills above here once held the tallest trees on earth, and every one of them was cut down. All the redwoods up there now are planted second growth. It is amazing how well designed these trees are at conducting fog moisture into the immediate ecosystem, even where official rainfall amounts are less than ideal. But they can also act like a big umbrella, and numerous times I've had a view camera propped up under one during a heavy rain, without me or my gear getting wet. Last month I was on Maui, where the mid-elevations resemble Marin County here, with open meadows surrounded by transplanted redwood an blue gum groves. I particularly like to play cat and mouse games with the lighting in the redwoods, which can be rather soft and mystical when the fog is present, and then rather quickly transition into hard and crisp, with extreme contrast lighting ratios, once the fog breaks around midday. The latter scenario will quickly separate the men from the boys when it comes to film choice and Zone System skills (plan on twelve or more zones, not eight! - sorry AA, but I don't believe in compensating developers - give me a long-scale film to begin with).
