"Don't be scared." San Felipe Warnings Or Dangers Tip by dabuwan
San Felipe Warnings and Dangers: 4 reviews and 6 photos
Along the road n.5 between San Felipe and Mexicali you'll see some of these boards, warning that you are going to drive through a "disasters area". Don't be scared, the road is OK and well paved. I'm used to much worse and more dangerous roads than this one.
Maybe you have to take special care during sand storms or heavy rains and possible floods.
