Thanks very much guys
TBod- yea its pretty dry here, we are close the divide in montana and its breaks and badlands to the east and snowy, rocky mountains to the west.
the logs themselves dont touch ground at all, its all on stone footers and walls but the floor will touch..but i am gonna cheat a little bit too, i am gonna use pressure treated lumber for the floor trusses, PT lumber lasts for ever out here. lots of people out this way use regular pine lumber or even logs with the bark still on for floor trusses...i'm not that brave.
