Hi @Calderfh , just found this thread. My family took a vacation to California when I was in high school in 1970 (yes I am old LOL) and we visited Muir woods. At the souvenir shop my Mom bought a burl and grew it in water for maybe 5 years until the shoots got so long they looked ungainly. Neat to see a burl again.
Did you ever go on a collecting trip with the other BonsaiNuts?
