Pat, Had your neighbor been drinkingIJ Seriously, I picked up a new 30' Harvest Hand with dual tires where they're made in Southern Iowa, drove to Northern Iowa, picked up a 25' flex head, and took it to the border of Kansas and Oklahoma. I suppose it was about a 1000 miles or so. I tried to keep my speed down to something reasonable, but there were a few times I was going over 60 mph and never had any problems with it weaving.
