Puerto Libertad is only 220kms from Rocky Point. That's just a gas stop for me. I continued to Kino then up to Punta Chueca, back to Kino, passed through Hermosillo and stopped in Banamichi to overnight. Still got in way before dark. If you're still in Kino make sure to ride to Punta Cheuca. Nice paved road with an incredible view of Tiburon Island on the way.
