Monarchs arrive in October for their annual migration to Mexico.
In all the world, no butterflies migrate like the Monarchs of North America. They travel much farther than all other tropical butterflies, up to three thousand miles. They are the only butterflies to make such a long, two way migration every year. Amazingly, they fly in masses to the same winter roosts, often to the exact same trees. Their migration is more the type we expect from birds or whales. However, unlike birds and whales, individuals only make the round-trip once. It is their children's grandchildren that return south the following fall. The descendants often roost in the exact same tree that was somehow passed onto them through DNA.
it is also the best time of the year to be out on the coast. I highly recommend a day hike to Morro State Beach and pfiefer falls. http://www.google.com/images?hl=en&q=pfeiffer+falls&um=1&ie=UTF-8&source=univ&ei=ZV9LTI6YBYrWtQOmj8RI&sa=X&oi=image_result_group&ct=title&resnum=4&ved=0CDIQsAQwAw&biw=1280&bih=685

and of coarse the Ventana Wilderness
It only takes one quart of oil to destroy 150,000 to 350,000 gallons of sea-water. Please know we all are stewards of our earth.
