It was a mess. I don’t have w/s wipers, but my A/C works great. The worst trouble I had in the rain was in Toledo thru the construction, where the mud was 6-8" deep. It made a mess of my engine compartment/undercarriage. There was more rain from Kalamazoo to Racine, but the rest of the week was perfect weather.
Next year starts in Little Rock & ends in Madison, WI. They only announced one other city - Lincoln, Nebraska. I do not plan on going next year. That’ll probably be a 4000 mile trip. We did 2700 this year, and that was enough.
