Let's make clear the whole PDC cost issue since it seems to be a hurdle, mentally, for most to get over.
The average PDC tuition costs $1200, as where Larry Korn's PDC costs only $800.
Lodging costs are approximately $25 a night, with full laundry, interent, kitchen, hot tub, shower facilities, etc. And that's the expensive option. You will not beat that EVER with any conventional option and most PDC lodging is pretty convential.
Oh yeah. Then all the food. Organic, cooked and catered, tailored to diet concerns be them medical or philosophical. That's runs about $10 a day per person, with full pantry access. Thats all your meals and snacks covered for the entire day for less than dinner at a cheap resturant.
But where does all the rest of the money go after the instructors, the chef, the food, and the facility? Well advertising, so you can know that this impossibly cheap deal is available, doesn't come free either. Someone has to make it, print it, publicize it, work the network, travel to post flyer, run a website, make connections, get Paul Wheaton's support, etc.
And someone has to do the accounting, and the regisration, and then logistics, and the menu planning. Oh, and the fees for guest instructors, plants, materials, demonstrations... Am I making myself clear?
And then there is the work trade discounts, and the scholarships so that genuinely intersted, and yet poor, people can come learn it too. There are no institutional grants and government subsidies for permaculture education.
So if you have thought to yourself, "Wow, that's a lot of money, this should be a community supported effort." Well it is. It's more of a community supported effort than most PDCs you will find out there and yet it's still having a hard time meeting quota.
