Just curious, but what is you intended use for most of the redwood that you saw, if it is soft and not very rot restistant. I remember it being used for decks years ago, water tanks and even the big industrial cooling towers were built out of redwood, I was always told it was because of it's resistant to rot. My grandad even had a 5 gallon water can built out of redwood, every spring I had to throw it into the stock pond for a few days to swell the wood, so it wouldn't leak.
