I'm in Mountain View, MO. Started from Union City, TN 3 days ago. Took the ferry from Hickman, KY and then did a long, long ride over the levees and bottomland along the Mississippi. Rode 50 miles and only saw one gas station. Nothing but farm land. Very, very few homes. You can ride for an hour and not see a car. I felt I was lucky to be riding this section with the temp in the 70's. 90's with no shade and no water stops would not be fun. (But it sounds like that's typical out West.) Be sure to have plenty of water when you leave Hickman. The ferry is a very small operation. I think it hangs out on the MO side until they have a car to carry or someone pushes a button on the KY side. Both sides use boat ramps. On the KY side there's a sign with instructions to push a button to call the ferry. I waited about 20 minutes and was the only one riding back over to MO. No cars. Just me and the bike. Call the ferry to be sure it's running before committing to that route (731-693-0201).
After an 85 mile day, I spent a night in Dexter, MO and I've been on Hwy 60, more or less, the rest of the time. From Dexter you can ride about 50 miles to Pinewood Lake Campground near Elsinore. A ranger told me it had just reopened and had a pit toilet and no drinking water. Camping is free. I camping on a mowed lawn next to the lake because the camping loop didn't look very inviting. From there it's about 60 miles to Blue Spring Campground (near Mountain View on Hwy 00 about 5 miles off Hwy 60), another primitive camping area.
I've had several opportunities to go up to the TransAmerica Trail but chose to stay on 60 because it's the fastest way to cover the miles. It's like riding on an interstate shoulder. 10 or 12 feet wide and mostly in very good condition. And the route is straight and the elevation changes are not as extreme. But, again, if the temp was in the 90's, no shade and not so much fun. Gas stations about every 6 to 10 miles.
I'm planning to get off 60 in Diggins, MO and then hit the TransAmerica in Marshfield.
I know I've missed some beautiful scenery on the roads in the Ozarks and Current River area but I'm fighting a little bit of a time deadline so I needed to cover some miles.
