Hey Mike,

I bought your book about 4 months ago and have just been really impressed by the detail and thought you put into it ( I especially like the engineering charts at the end; they are super helpful).
I wanted to propose another method for the wall construction namely earth bag walls that have been cobbed over.
The reason for this is two fold: 1, I feel that it would add another layer of fire protection to an already fire resistant home and 2, it would be an option for those without access to mill ends or a method to have their trees milled.

What are your thoughts on this?

My thoughts are entirely supportive, though I might incline more towards earth tubes. -- MO

Thanks for the advice and the support.
Good luck in all your endeavors, you are an inspiration.
