well I'm all signed up and starting my basic irrigation course tomorrow. the class is being taught by Dave McCullough (irrigationclass.com) in Houston tx. I can honestly say i know absolutely nothing about irrigation at all. And i have no intentions or plans on going out trying to bid installs or designs anytime in the near future. i am only taking this class to gain some knowledge on these systems and taking the next step to becoming a better lawn care provider. i have learned a lot from lawnsite and there is some real pro's on here that shared a lot of information and tips that have really helped me along. I am new to the the irrigation forum and hoping to be able to ask some questions now and then to help me through what i have read is one tough course. Thanks mike.
