Day 4. 330 miles today in mostly pouring rain. Now I have covered 1,688 miles with over just 600 to go. I'm just short of Oklahoma City.  "I can hear Shirley Jones and Gordon MacRae singing now. "You're doing fine Oklahoma". No pictures today because I felt like a drowned rat. Met a Harley rider from Manhattan at a rest stop. We chatted for a while then headed off in different directions into the rain.
