It is the best course I have ever taken and probably one of the best things I have done in my life so far, for a number of reasons, but mostly because the knowledge we gained in the class is invaluable and cannot be bought or acquired anywhere. I thank you also for bringing a lot of energy into the class and you made it fun to be there... I think everyone should learn about organic gardening and organic living. I want other people to learn the same things I did and then educate other people as well. I think with this "snowball" effect, we might eventually have a large percentage of the population engaging in organic gardening, which would be amazing.
