The heat wasn't too bad - I left Hermosillo early in the morning. Yes, I took every libre opportunity to Los Mochis.
The next day, Los Mochis to Mazatlan, I took libre half way, and the final dash from Culiacan I took the cuota (which was a mistake.. nothing to see at ALL). It was 90-96˚ the whole way. Not bad :)
I also realized I had my seat adjusted incorrectly, so I was rolling forward slightly. After raising the front, I was much more comfortable!
I'll be here in Mazatlan today and tomorrow, then Puerto Vallarta (sigh, I promised someone I'd visit).
THEN! Then, I make my way to Oaxaca.
