Unfortunately, those lovely sand roads are separated by less lovely sand roads, and to avoid the latter I was on some pretty busy ones:
Here's one of the smaller sand roads... this is definitely the road not taken:

But there are some beautiful roads with almost no traffic that are, against all expectation, nicely paved. Good names, too! Here's one end of Mount Misery Road:

And here's the middle section:

At the northern end, the going gets pretty tough for a while:

And before too long I'm back in the open farmland.

See how the weather started to deteriorate? There were now clouds in the sky. Oy!
Gratuitous art shot:
Oh, and check out this. It's for sale! Pretty cool, huh? but it's not as old as my bike.
Got home at 5:30 PM.
According to my Veeder cyclometer, I had gone 116.5 miles. When I started, it read 1100 miles (I zeroed out the top part). I like these old mileage tickers, though it's often hard to tell what size wheel they're calibrated for. Period correct, man!

I also used a Mavic cyclocomputer to calibrate the Veeder, and the Mavic gave me 121 miles. But then I plotted it out on Ridewithgps, it was 116.7. I think you can find the route
here.
