My copy of Soggy Sneakers by Pete Giordano and the Williamette Kayak and Canoe Club (Fourth Edition) came in the mail from Amazon today. I bought it with the Oregon DeLorme Gazetter and the total came to around $30 with shipping. Definitely worth the $ in my book. I must admit, as the previous poster did, that I am a fan of guide BOOKS. There is certainly a lot of beta that can be found on the internet and I'm not luddite and do in fact use it for flows, etc. even on my phone, but you can't replace a book for leaving on the dashboard and having the navigator scope out the next run.
One thing that really works for me in this book is a watershed map. After very little previous travel in Oregon I couldn't get an accurate lay of the land. One 30 sec. glance at the watershed map and I feel a lot more dialed.
Now, the most important thing... how does one pronounce Williamette. My brother-in-law is an Oregon native and he says Will - AH - mette. I was prone to say Will - am - ETTE from reading it. I'd guess he's right
