Here is what I just posted on the La Peñita facebook page.
Just got to Shadow Ridge RV park in Ajo. Road was generally BETTER than I remember it from pryor years with a few exceptions. From the park to Mazatlan it was pretty good except for the known bad spots. Maz to Los Mochis was pretty smooth, just get in the left lane and stay there. Mochis to Guaymas, not too bad until you get over the hill past the toll north of Mochis, then rather rough but doable to the state line then better to Navahoa, then good concrete road to Cd. Obregon. Obregon was the usual joy to get through, then the WORST stretch on the whole trip from Obregon to Guaymas. Guaymas to Santa Ana was OK, usual crowded road through Hermosillo, breezed through the checkpoint. Lots of two way traffic. Sta. Anna to Caborca was smooth to Caborca, then the first 40 or so miles to Soynota, had some pretty bad chuckholes but avoidable if you keep your eyes open,and a few really rough spots but you can see them and slow down, then the last 50 or so miles was pretty good.
