We started early today based on the forecast of building winds late in the day.  By noon we were encountering sustained winds in the 20’s with gusts in the 30’s and predicted as high as 50.  Incredibly these were actually less bothersome when the route turned and they were hitting broadside.  When they were at a 45^O to head-on they really messed with forward progress.  It seemed like we were going uphill all the time.  We gained some altitude and even crossed the Continental Divide at around 4,500 feet but the wind made progress hard fought even on level ground. The predicted dust storms were never really a problem for driving but “dirt devils” dotted the horizon and not-so-distant mountain ranges disappeared at times.  I was a little surprised when the weather radio noted the dust would subside and “visibility will improve after dark”.  Days like this make be glad we have 16 ply tires with 105 psi on the motorhome, even if they do ride a little rough.
