What an excellent blog! I particularly like the collage of John Muir since the Muir Woods are located just 18 miles (29 km) from my home in San Francisco, CA. Maybe one day you can visit the magnificent trees located in Muir Woods – the tallest tree is 258 feet (79 m). The trees come from a seed no bigger than that of a tomato. Most of the redwoods are between 500 and 800 years old. The oldest is at least 1,200 years old. Definitely a sight to see!
