I was in this class as well, and will second Aldo's positive feedback and then some. Shawn is a great Instructor... Very knowledgeable and passionate about what he does, and the quality of his class reflects that.
This is a physically challenging class, no question.... There were a couple times I didn't think this fat guy was going to make it through the drills. (Felt some muscles get worked that I didn't remember I had) :-)
I knew very little about this topic going in, other than having a couple basic first aid and CPR classes over the last several years.... I learned ALOT in that one day, things I had never thought about, or have never been exposed to. Of course much of it you hope you will never see :-) (Unless that is your career choice)
I highly recommend this class to someone who wants to do some unique training that is great stuff to know.
