I want to audit this class.

My wife went to a class today about identifying bombs and the materials used to make them.  When I first heard about the class I wanted to audit it. 

I flipped through the materials (I haven't had time to do more yet) and was somewhat surprised.  To make an IED the list of things available are also going to be in the car of anyone that's going to manufacture their own meth.  It also didn't list some things that I know can be used for a simple IED, I don't know if it didn't have it listed because it's not as lethal as some of the other materials (huge amounts of fertilizer) or because it's just that under the radar.

I still want to go to it next time.  My wife's only complaint about the class was they didn't get to blow up anything.
