As another student of CRMPI I feel compelled to share about my experience with their PDC, as it was much different than Johns...
I took their PDC in July 2015 and it was one of the best courses I have ever taken. I am someone whom needs to see things in action in order to understand them, and that's why taking a course works for me, instead of just reading information about permaculture. Before the course, I had only a basic understanding of the permaculture principles, and I left with so much information, a notebook filled with ideas and concepts.
I felt that the course was completely comprehensive, I loved that the instructors addressed topics beyond agriculture. Sure, I could read all of the books written on permaculture and probably learned a good chunk of whats out there, but a bonus to doing a course is the connections you get to make and ideas that come from the others there.
I can see how someone might think Jerome is maybe unprofessional or sarcastic, but you know what, he's not a business man, and thats one thing I loved about meeting him, you see his love for life and plants beam out of him when he is doing his work. He loves nature, he loves simplicity, no wonder he hasn't focused on setting up a paypal system for the course!
I also loved the facilities (I will admit, we did not have to use a porta-jon). The intimate setting of the class room in Jerome's house made it easy to get close to each other and make connections. It was awesome for me to see that this place was primarily a home, and then secondly, an education center. It made it clear that a home can be an education center. The green houses were amazing, I mean, to have tropical fruit growing int the high desert is an accomplishment. Doing the actual work was a bonus for me, too. I enjoyed when we made swales, grafted trees, mulched the garden and acted out scenarios. This helps solidify the information in my brain.
I also loved the field trips we did. We got to see a variety of alternative buildings in the area which instilled so much inspiration in me.
I am someone that does a lot of research before committing to something, especially when the price is high, and I thoroughly read the CRMPI website before signing up. I did not feel misguided at all. Camping is camping, personally, the fact that we had access to a home, made it not even seem like camping...The activities we did were engaging and dynamic. We got to do actual projects for actual clients in the area. I felt taken care of and supported the whole time. It was a beautiful experience and I would really hate for someone to miss out on it. It's not your average university course, it's an interactive experience at living a permaculturally-focused life. I am forever grateful for the facilitators at CRMPI and my experience there.
