I received my copy of the book. It is fairly short and half of it is a reprint of ORS and some letters clarifying some legal points. So the actual text is about 23 pages -- I read this in one sitting over one beer. Mmm, Black Butte Porter, frosty chocolate porter.
But I digress. It does indeed explain the laws in plain English. I wish it had more resources. For instance, they recommend getting more training than just the CHL class, but don't have a list of places in Oregon to go for more training. I know of places, but if I were new to this, it would be nice to have a brief list. Also, they recommend having a good, pro-gun lawyer in case you ever are in the position where you have to defend yourself. Again, no list is given and I'm not sure how one goes about finding a pro-gun lawyer.
It's not a bad book to add to one's library.
