Day 4 - Bill & Bea's Burgers

June 20, Millersylvania to Rainbow Falls State Park, 39 miles
 The rain didn't stop in the morning but it wasn't cold and I had rain gear.  As I departed, I could see that the campground had filled up overnight.  Kids everywhere on their bikes; the smell of bacon and pancakes mixed with the wood smoke, made my mouth and eyes water.
 I couldn't resist stopping at Bill & Bea's Burgers on the outskirts of Centralia.  I was not disappointed. Although navigating through Centralia wasn't fun, the fun did begin when I got onto a pleasant, hilly country road dotted with horses, cows, sheep, and John Deere tractors.  The last 15 miles to Rainbow SP is on the Willapa Trail, which I mentioned having traveled last year.
