I'm about to overwhelm you with more info than you'll ever need ......
check out http://www.cyclingsite.com/lists_articles/ and after reading these, if you want more, go to the homepage and start reading. Bob & Rox set up this website a number of years ago, to gather info about Cycle Oregon and to help first-timers get a feel for what they were getting themselves in for. They had so much knowledge that they wanted to share, and wanted others to have input as well, and so it came to life. Even though this site has been around for about 10 years, every time I go there, I find something new I had not read before. (and yes, the Edna mentioned in emails and such is me and Dave (Slug) is my DH).

Happy reading and enjoy your tour.
