Got it! ! ! I just glanced thru the post about I-5, snow, hwy 101, etc and assumed you were towing the boat.
If you are not comfortable on the northern part of Baja you might consider going from Tucson, Az to Guyamas/ San Carlos, Sonora about 300 mi of good divided hwy and a great marina in San Carlos. We have a C- brat that registers San Carlos as his region.
Rick and I have though about towing Amigo II that way, looking for warm weather and blue water. It is about 80 mi across to Mulege.
I'll be watching for your post.
