'Twas a great ride. Got out later than planned, but the sun didn't burn through until almost 10. Was a little bit busy on the way in to Viola, but there's a great rest stop/store (closed on Sunday) at mile 30-center of Viola. And then very little traffic after that. Great scenery, no long stretches of rough paving, minimal dogs.
Turns out to have stores at 16, 30, and 41 miles. And I added a stop at 54 miles where I know the business owner. 63.8 @ 14 is what I clocked with nearly 1.5 hours consumed with stops. Flat to rolling with more rolling than I expected.
Will have more data next time with GPS unit now installed. I'll definitely be riding that route again.
