I feel your pain. I carry around a bag full of worthwhile goodies in my daypack when I go caching. But about 75% of the time, I TNLN because most caches are literally filled with worthless McCrap. What is it with you people who take all the good stuff? Trade up or even! But hey, most of the fun is the hunt and the find, no?

I don't know of any one-size-fits-all book. Oregon is so diverse with the coast, coast range, Willamette Valley, Siskiyous, Cascades, high desert (basin & range, Columbia Plateau), etc. Two books come to mind for the Cascades: A Field Guide to the Cascades and Olympics - Stephen Whitney Cascade-Olympic Natural History - Daniel Mathews Also check out the Nature of the Northwest at www.naturenw.org They have a store near LLoyd Center. Check out Powell's Bookstore. Good luck and good caching!
