Chase is a great guy, and teacher. I took my first bonsai class there with Chase many years ago. Introduction to bonsai, that may not be the name exactly, but, same info.
Chase taught part of the class, and his wife Solita, taught the other part. Great class, if that is the one you are taking. First thing I learned is that I didn't know half the things I thought I did.
I have taken many classes with Chase and others over the years, and guess what? I still find myself saying, "you don't know half the things you thought you did"
Have fun in your class. Watch and listen to everything he has to say. He has been doing it for a long time. And by all means, spend some time walking around the nursery. He has some great trees there.
