Aug 20, 1933 Driving a few miles on these muddy ruts to an immense stream, largely makes it is next to impossible to start the car when the mud is deep. Fortunately we had no major mis- gos this morning. Once the engine I wet and died in a large mud middle. Another time we were stuck deep sloppy mud and pulled the car out with the block and tackle. The spot about which we had been wined last night was still bad this morning. There were still two huge trucks badly mired in. However it was easy enough to bypass the mud by driving on the railroad trucks, which we did. The rest of the way into C. Obregon was easily driving since the rain had not moved this far north. Happily enough, the pango at Cocoyot had been repaired and to our great surprise, the highway was paved to the Rio Yaqui. A DOR Hyparilous (not saved) was the only snake seen in today's daylight driving. This was 26 mile N of Obregon.
