Query: Why pay?

The book took some work, it is well written and illustrated and mostly accurate from what I can see of the local state parks mentioned. All that said, I did not get any information from it that I could not get from free publication from the State Parks themselves. If you intend to visit a number of Oregon State Parks at a time then this may be a good one stop publication that has a little back round information such as " one of the few State Parks not to have a sign at the entrance" (Bolen Island, actually it does)but all the pertinent information you need is available from Oregon State Parks for free.
