That was my guess, from intuition and confirming with the elevation map.15 following the river is probably flatter.
That is exactly the kind of tip that I love. Thank you!If you guys want a nice drive in the country without the turnpike construction. Take route 303 east out of Streetsboro Oh. (you will have to go east on 14 for a mile or so). Follow to end, make a right on route 82, and follow to route 11 for a couple of miles and it will drop you on 80 east of Youngstown Ohio. Literally parallels the pike and is much more scenic, not as boring is 55-65 mph except for couple of towns.
How about continuing a bit further east on 82, then take 7 down to I-80 (another 3-4 miles east of the intersection with 11)?
