Great post Philip.
Although I've passed through Spokane, I've never 'experienced' it. From what I saw, it seems that there are patches of conifers strewn about, especially north of there. I seem to recall Richard Black saying that his pine needle droppings were providing acid to the soil. Perhaps you can do without the sulfur?
In any case, it's always good to hear of char experiments. I must admit that I'm a bit jealous.
Hopefully I'll have some garden space for next year. Perfect time for newlyweds to buy their first house right?
Living vicariously,
