We did the La Sal Loop that brings you back to the 128 and in short order wound up behind a 40' moho. It is a very narrow road with lots of twists - have done it several times in the past. Moho was going slow and could not get around of course as they had really no place to pull over if they wanted to. But we felt safe he was well over the center line most of the time so I just sat back and let him clear traffic the other way. People would wave at him with their right wheels well off the road............ well, kinda wave! :-)
