I bought an old building 40 years ago. It came with a old 40 foot wood extension ladder. It was tough to move around and I was young and stronger then. You'd think wood ladders over 10' would be obsolete for many reasons, right?
Wrong:

"Longevity is another plus for wood. Although the life of an aluminum ladder is 15 to 20 years, Braun said, San Francisco’s oldest wooden ladder still in continuous service was made in 1918."
They still make and repair there own ladders. They regularly use a ladder that's 99 years old!
Very cool to see wood products appreciated like this.
