We are at La Paz (and finally in the Sea of Cortez).
The dolphins are amazing! The species of dolphins we've seen the most are common dolphins (look them up!) They ride the bow more often than most other dolphins. One night we were sailing along and there was a little bit of bioluminescence and dolphins rode our bow for half an hour, and one jumped all the way out of the water!
There were manta rays at the last place we stayed and they were doing flips out of the water!
The picture here is of one of the boats we know getting rubbed by a grey whale.
