Day 4-Coralville, IA to Erie, PA

​Day 4 of Connecting US 20 eastbound was a tough one. Construction in Illinois, Indiana, and Ohio slowed us down, adding about 1.5 hours to an already long day. Highlight of the day was our lunch at T-Bones in La Porte, IN. Sally had eaten there when she was at a residency in Indiana last year. It was 7 miles off the freeway and we just happened upon it. Paid nearly $25 in tolls across 3 states; weird occurrence for those of us who don't pay a toll anywhere in Oregon. 14-hour day; 5 states, 1 Time Zone, 669 miles. 2617 so far. Erie, PA overnight. Niagara Falls is Day 5's goal, about 120 miles away. Get to be tourists for a day. Yay!
