We'd been driving in Minnesota and decided for some variety on the way back to California, so headed down I-29 through the area hit by the spring Missouri River floods.
The Iowa DOT detour signage sucked to the tune of 200 unneeded miles and four wasted hours of circling thru cornfields. We'd still be there if we were to follow their signs, if it hadn't been for a couple of traveling salesmen we hooked up with at a country gas station.....they were headed to Kansas City, as were we - "Follow us!" was the call of the day, and it worked - we ignored the 'road closed ahead' warnings and got thru just fine, as did all the local traffic..................found out later that the Iowa DOT didn't want to "stress" any one local country road with too much traffic, so this bullshit was all intentional.
It can be good to tack away from the fleet.
