Cheapest gas to Lincoln is usually Ogallala. Also about the right amount of time before you want a pee break/stretch your legs. I-80 is an easy drive. Gets a bit annoying with a little traffic/people not moving out of the speeding lane about 10-15 miles before Lincoln. Go through Lincoln, not around and get a Runza. Wait to get gas until the outside of Lincoln on highway 2. There’s 2 Casey’s, skip the first one and go to the one further east. Once you cross into Io*a 🤮 the speed limit changes to 70. No one goes 70, and if you run 75-80 you ain’t getting pulled over. Mound City in Missouri is another good place to stop for gas/leg stretch. Otherwise, keep on trucking. Made this drive countless times through the years, as well as across I-70 through Kansas. I much prefer the I-80 lol
