here's a better shot of the tree from a ways back. Some people from the area might recognize it as you come into calistoga.
I thought maybe 80 - 90 ft to the top but when I got my climb line to the first couple limbs it was 60ft. Fun easy climb, you could practically walk up the tree in the upper sections.
That is a really cool idea, putting a flag 90 feet up. Is that in Hawaii? I will be making a trip out there within the next few years, and always open for a fun climb with the lil lady.
