Welcome to TreeBuzz Diogenes. Thanks for posting here, I'm overdue on posting a couple of thoughts I wanted to share.
I went to both the Santa Rosa workshop and a couple of hours away to the Sacramento workshop the next day. I did this because I think the pruning info presented is so valuable and I wanted to learn as much as possible as soon as possible. Excellent examples were given of pruning and its corresponding results via pictures of the same tree in subsequent years.
Mark did not only a practical presentation of SRT enabling him to easily get to outer edges of the canopy, but also a very useful talking presentation on professionalism. His in tree demo helped in seeing what is physically possible, expanding peoples horizons - some it seemed for the first time. His talk on professionalism hit the mark for our industry as a whole in my opinion. If repeated enough times, and adopted by most, the concept he shares has the possibility of raising the tree industry to a whole new level.
Anyone able to get to the Southern California presentations, I would highly recommend it.
